#WashTastic - 1W node based on E22-900M30S and promicro NRF52
1 messages Β· Page 5 of 1
hmm
maybe smaller
1.5mm pitch
nvm
thats surface mounted
@olive basin Once you start getting your boards sold, you should cast one in acrylic.. LOL
I mean I'm already selling in small quantities
Are you making enough to cast one ? ;P
I was watching How It's Made, and they were making Acrylic awards.. Thought it would be cool to do that to one of the nodes..
i mean sure i can put in a picture frame or something π
funny enough i have 3 different iterations of this π so i could save em lol
soon fourth lol
β¦so anyone selling these stateside?
I've been wanting to place an order for some..
Not yet, i might be selling these st somepoint on elecrows store
If anyone decides to break the seal Iβm down for 1 or 2

@finite palm hows the v0.4 working?
i'm here debating if i should go with 0.3.5 or 0.4.
0.3.5 is cheaper ish but it requires elecrow to do more work
Heya @olive basin ! π I've got one MIA and one working perfectly!
The one that's been deployed where it's hard to get to disappeared off the mesh a few days ago with 50% battery remaining... unforutnely I haven't had a chance to get to it yet, but will debug and report back when I do!
The one in my yard is working perfectly - no issues at all! It's running stably and is keeping its battery topped up!
Are they flashing everything also ?
Apparently they can flash everything
Is that extra, or included in price ?
Interesting, i have one node has full charge and one doesn't seem to charge. Could be panel in a bad place
Probably extra, haven't asked
dumb question: how thick is an assembled washtastic?
ummm.....
ok I dont feel so bad if you dont know lol
just trying to determine minimum clearances for a case.
well the board is 1.6mm plus components
https://zipline.valzzu.xyz/u/BdyvRZ.png
I'll just say 10mm and have good clearance π€£
Thickness depends on what components you install also.. Like I have a wash board w/ pin headers so I can remove the promicro.. That adds a good 1/2" to the hieght I think..
Good point, thanks!
You can get reduced height ones... 3mm sockets, 2.5mm pins
okay, i got a question, if i swap the b,e280 to aht20 are ppl gonna miss pressure reading?
aparently it doesent need standard assemlby so u save $25
and its cheaper than bme280 anyway
I pref pressure, but that's me.. What bout a shtc3 ?
Wait... That doesn't do prwssure..
BME280, 680, and 688 seem to be the only ones that do pressure..
https://zipline.valzzu.xyz/u/AUfT18.png
https://zipline.valzzu.xyz/u/AX85gC.png
plus $25 for standard on bme280
plus $3 for extended component fee
loading
Geezz...
yeee
One person managed to break the switch π
They have no idea how they did it
It was just missed π
Yes i did tell him the battery is wrong way π
$560.58 for 20 on elecrow with promicro soldered and flashed
that would be 28β¬ per node
Yeah, I broke one trying to shove it into a case. π It's quite fragile.
i prob should replace it with maybe ine that is pointing up π
Hmmm I just inspected the one in my yard today... interestingly the solar charge LED doesn't appear to be coming on anymore... but charge does still seem to be holding up π€·
Haha yep, if anything it's optimising power usage by not running the LED...? π
"Its a feature"
you can use OPL part numbers, that would be the equivalent of LCSC numbers
i now have 3 that wont find the lora module π
I'm happy to announce that u can now buy washtastics from Elecrow once production is done
https://www.elecrow.com/washtastic-nrf52-powered-and-solar-ready.html
is always the promicro
wick and flux should work, with flux you get more tension on the sn/pb solder paste, and the wick absorbs it
nope.. I'm a hardcore player
U was suppoed to be i lol
mmmm
is a bosch tool, usually 40β¬
my dad has a hotair gun
but have to be careful, is a lot of heat
tho, i dont have spare promicros π
also I lost Q2 in this board (maybe the air draged it..) but I wasnt adding gps anyways
also the pins missaligned so I had to manually align them. In anycase the board was already lost with a failed promicro so was worth trying
Oh I just remember
Unsolder needles
This are tiny tubes of different sizes
https://a.aliexpress.com/_Ev0vPwm
You heat the pin and insert the needle in the space petween the pin and the hole, physically separating both
Move it until it cools down. Pin is unsoldered. Profit
I forgot I had of these at home
Those look easier than using a fine-point soldering iron and stabbing it through the PCB until the edge unzips like a cheap handbag.
Dem, somebody downvoted
Are any of the 0.4's going to make it up there? I'm interested in experimenting with those
On elecrow? Nope
atleast not anytime soon
Rly gotta make a video showcasing WashTastic π
Actually I found you project by chance
I was looking into poweful meshtastic. At first I found the ndoo web that pairs a xiao and a E22, and used xiao_ble variant. nice documentation but didnt want to get into all the pain of installing kicad, jlcpcb plugins and so just for a pair of pcbs, so I mounted my xiao_ble manually wiring it following the README in the xiao_ble variant folder.
then I found your board
I was already mounting CN3791 solar board on my tube nodes and I used a step-up buck to feed my E22 in the xiao_ble, so to me you board was perfect, had everything I needed.
basically, googling e22-900m30s meshtastic, drops a lot of pictures
Hahah
Many do
but ad video would be cool
This board should have its own variant to define the use of the e22 and properly set power on the firmware.
maybe yes but idk
would it be in the flasher?
tho if it had maybe it could have its own portnum
π€·ββοΈ
Your own hardware id sound cool
#1295160974751432705 has π
but it might have private HW tag
that would be cool too π
since theres not alot of those
that's the one used by devices that does't have a hardware definition
for example, the xiao_ble
I have one xD
Un mapa interactivo de todos los nodos de Meshtastic.
is the meshtab more popular than the washtastic ?
then washtastic should have its own variant and its own hw id
that was made before any changes was made
well... if no one has ever built a mesh-tab, you could ask to repurpose the id 86 for the washtastic
nothing gets broken
right now the washtastic may not be very popular, If you define your own variant you can referer to it with the 255
and eventually if it gets more popular have a hw id for washtastic
I think that private_hw is not included in builds
you can not get precompiled build for xiao_ble for example... I had to compile it myself
board_level = extra makes it so its not built
oh I see
I guess that depends also on the popularity
still you need a variant π
She has a variant - she's been savvy and used one that is already built π
having to set the power in the firmware to 20 instead to 27 is an odd job
Yes, but it's only one that has recently become automate-able
which one? I only see the mesh-tab
The promicro
Washtastic is a promicro board
variant != hwid
can the promicro variant be configured to use E22 ?
oh sorry, you mean use the id promicro in a washtastic variant ?
I still dont get the firmware guts, sorry
The variant is just the configuration of the pins
yeah and in that term theres no difference between the promicro_diy that's been using in faketec
The architecture, the pinout, and some hw specifics like power switches and stuff, and then the rest is the base firmware, based on if it has screens or buttons or whatever
exactly
they share the processor and pinout, so why give them a different ID?
but sharing same pins with an ht-ra62 doesn't mean that the radio module is actually an ht-ra62
They both have an SX1262 radio
with TCXO
(and even if one didn't - the code allows for that)
but their sx1262 are configured differently depending on the PA
the major difference is the PA on the E22-30db
if meshtastic is trying to keep radio inside legal term, burning a faketec firmware in a wastsatic will result in someone fixing tx power at 27 in firmware, which will result in 22 in sx1262, shich will result in 30 (1w) overcomming the limit
Faketec uses promicro firmware.
User takes responsibility for reading the instructions.
The police are not going to knock down your door over 500mW extra
then stop limiting power based on the legal area ΒΏ?
they will knock politely
that's a contradiction itself
that the police will knock politely?
'limiting tx power based on territory' and 'user takes responsibility'
========================= [SUCCESS] Took 99.17 seconds =========================
Environment Status Duration
------------- -------- ------------
WashTastic SUCCESS 00:01:39.169
========================= 1 succeeded in 00:01:39.169 =========================```
Up until recently, it wasn't possible to even tell the firmware that your radio had a PA - you could only limit the maximum power to something lower.
The user had to take steps to limit the power output themselves.
Have the convo, and get it submitted (with power limit included π )
@true garden are u able to test Washtastics own firmware? so that the lora tx power works correctly?
sorry for the confusion, indeed hw id is not the same as a variant
I can try if I get some time just got back from overseas and daughter is sick currently
no hurry
It's fine - I've been doing this for 2.5 years, and I only realised this like a year ago
@swift wind made a pr
https://github.com/mrekin/MeshtasticCustomBoards/pull/7
tbh, did not know i could do it
plus i just remembered vardas had the flasher and could add it there
hopefully the variant comes into the official repo
@severe halo https://mrekin.duckdns.org/flasher/
Easily allow users to install the Meshtastic firmware on the web.
Daily build
2.7.4
nope, they just have their own "flasher" where u can download certain firmwares
oh, so you have yet to push it to main ?
talking with devs about it
I'm grounded on testing until I get those nice boards with gps and filter
I've been spending too much this month xD
ouh yeah
PCBA and everything.
@olive basin
share a screengrab of the breakdown
The parts alone cost about that much
Unless they've skipped the NRF or the E22 or somethign
No, it was both sides assembled..
This is $5.68 per board. The processor and radio combined cost more than this.
I know!
Screenshot via DM?
and bom and P&P?
Yes, bom and PnP..
Tho I just got a msg saying the audit failed, asking if the PCB is 2 or 4 layer..
You would think PCBWay would detect that from the gerber files uploaded...
It was what was on the site when I submitted order.. Trying to get the order approved..
It's asking if it's a 2 or 4 layer PCB..
ah yes, it will get more expensive once they review it
0.4 is 4 layers
We will see..
@olive basin When I select 4 layers, I get this..
idk π leave it empty as they tell if u dont know π€£
u could open the zip file and look
Ok, w/ 4 layer it's closer to 160 USD..
Waiting for Lyra to get back to me.. She's my sales rep..
it will get more expensive cuz the components
Right now it's roughly $8/unit..
Last time she got back to me in like 15 min..
It's around noon there, I think..
https://github.com/meshtastic/firmware/blob/master/variants/nrf52840/diy/WashTastic/Platformio.ini π₯³ππ
Woohoo
Iβve been away for a bit whatβs been happening! I got one of the V1 nodes but there seems to be a lot more new things
yes
yeah I saw it. Who knows... a matter of popularity
anyways I'm good, can build it myself. And also theres mrenkin
just sell more!
the video is a good start
and doc
who's offering 1w out of the box commercially?
station G2 is more than 1W but meshtastic limtis it to 1W iirc
but mines first with nrf52
new boards finished production and shipped this morning yay
oh nice
tho i'm bad at making anything good π
if you can handle cad design you can handle video editing with something like shotcut
and nowadays internet is full of AIs to make animations and so
bare v4 pcb is asking $7 for 5qty O.o
u can get 10 v0.3.5 for the price of 5 v0.4
theres not much i can do about those fees
yeah I know, but the price was so much offset that I wanted to see where was the difference. I though (influenced by you ¬¬) that it was because the PCB is 4 layers... but clearly the problem is that those components aren that usual and have to be manually configured in the assembly machines
they cost you the same for 5 than for 100 pcbs
the trick is to make a kickstarter and order 100 XD
yea i know
@olive basin Hi
Your commit in master with new variant little bit incorrect )
need to rename Platformio.ini -> platformio.ini
now platformio can't found it variants/*/diy/*/platformio.ini
I'll remove your variant from my repo, but keep fw building
lawl
idk why nobody saw that mistake before u π€£
May be I first who tried to build variant?)
On windows I usually get errors related with long paths with custom variants ) and don't have such problem on linux
@swift wind fix is merged now
That explains.. windows is not case sentitive
Swings and roundabouts.
windows is good in some things and not in some others π€£
anyone running these with meshcore I donβt feel like Iβm fully hitting 1w on meshcore I might need to adjust some settings
afaik no
boo
Wrong discord...
Agreed
Danng you guys be hating on meshcore π
No, I was just taught there's a time and a place for everything... for that topic: it's not here and it's not now.
I have a couple Washtastic running on MeshCore, unsure about power levels.
Cool thanks!
I dumped Windoze in favor of Linux last December. Haven't had a reason to go back since then. π
Is there a place people are sharing pics of nodes they have build with these? @olive basin
#1346425369246302258
Thanks
Np
Hello.
I have no clue why I have V in both JST but board is not turning ON
Flip that switch :)
DTP?
Nothing.
The promicro should have red blinking light
Is the battery charged?
Also why don't u have the connetor on it?
Yes, just removed for better testing now. batt is charged
U were one of them who ordered from etsy?
Yes
Maan im pretty sure that worked before i sent it π
Check on those pins
Should have the same voltage as battery
Not sure, 0v. Looks dead π©
Fuuuuu...... Okay, so its not getting any power
Then on those
If there is on one of those then u can bridge the 2 in the circle
at this point I would test right starting from the JST connector
and also try connecting the battery with reverse polarity and check if the warning led lights up
tru xd
Hmm Haha thatβs over my head π
Does it charge the cell if you plug it in to the promicro?
Just wondering if the ship mode has activated.
Try removing the battery and plugging in the Pro Micro via it's USB-C
Plugging in a LiPo, albeit protected, with exposed female header sockets is very sketchy
Iris meant the voltage between one of those pins and GND
@olive basin do you have battery protection on the PCB too? Does it switch VBAT or GND?
U3 is the xb80xxxxxxx switched-gnd chip
@left mirage Unplug USB-C if you put it in. Connect the LiPo. Check the voltage between the top pin circled in green (the one above the B+ text) #1315666061416464465 message and the pin opposite that (the one above the B- text). You should get close to the battery voltage
0v. While pins out JST at 3.8v
hmmmm
i wonder if the battery protection module is not letting power through
if u can connect atleast 5V on solar and try if that works
About to receive it
This is why I said to test at the jst. If there is some short in the board, the bms kicks in and shutdowns output.
i do test on the jst π
Oh sorry I missed the test by sovereign. I though it could be the on battery bms. So it could be the onboard bms⦠maybe test for resistance at the onboard bms output
The jst had voltage so its the onboard chip
Could be in over discharge mode π€·ββοΈ
Ship mode is where the BPC is in uvlo mode (overdischarge mode) but the battery is charged. You unlock it by charging a little bit, it should release it.
Basically, keep the battery connected, and connect usb-c to promicro
Yes
Saw this come in i was dem π
Is that the result of selling 5 units?
it also includes shipping
In my spanish comunity a couple of people ordered from your etsy last month following my advice.
Another one tried to do pcba but got lost in the process π
ah ahaa
so u made them order π€£
they bought the last units i had xd
last working once
Yup, is the only ready to go 27dBm that is not a G2, and the G2 is ESP based.
tru
I am recommending your boards a lot. Next hacker space Iβm surely selling some. To help funding my knowledge π¬
Btw this week Iβm expecting delivery of the 0.3.6 with the gps
awesome
any chance theres a iBOM laying around of v0.3.2?
@olive basin - Any idea what I might need to check again if I'm getting busytx'ed to death, and my battery input won't power the node, nor will the charge light come on when I have a power supply on SOLAR and a battery on BATT.
yep
could be dead promicro on the busytx thing
well not dead but not fully working either π
nope π
i forgor what that version looked like
could i get a pic?
@olive basin ^^^
So it won't power off solar (doing a 5V DC in for testing), and it won't power off a fully charged battery. Reheating all my pins on the ProMicro now, and I already reseated the CN3163, the MT3608 and the XB808. I do have some concerns about the pads under my MT though, i tried to wick up some excess solder and it looks like it just smeared it between pads, but i can't confirm yet. I'll break out the microscope after to check for sure.
Oh ye its one of these
3.2 should have the fixed version
https://github.com/valzzu/meshtastic-pcbs/issues/9
I wonder what could be the issue
it's a near full battery though (4.17V). And the fact that it won't power off solar is confusing too.
i have 2 (or 3?) v0.3's that are running fine. I have one remaining 0.3 thats bare. If i can't figure this out i'll just strip the board and use that one.
It's charging always?
not sure, ive done everything but break out the multi so far lol.
reheating all the pins didn't help. Time to redo the entire thing on the v0.3. There's no obvious issues that i can address, so.... this was the first 0.3.2 I tried to build, so i might have gotten some values wrong... i don't think i did, but still...
Sadge
Ive got 3 boards with busytx/rx of death π
All pins are connected
One person also had that and the only fix was changing the promicro
im buiding one fresh so i'll try that after, but i have a feeling its not that with the charging issues i'm seeing.
still not sure what happened with 0.3.2, but the last of the 0.3 boards is working perfectly
Great
now i can try to figure out wtf happened to the 0.3.2 without stalling my project more.
I made the right call on leaving the gps for assembly at pcba and mounting the e22 by myself
Let me know if everything works
Not rly
ah shet
the filter... is going to be really hard to solder
the pads are all under the filter
it would be nice if trhe pads were bigger
like the ones on the e22
had to scratch my way in
that was tight
I dont know if its because the solderingβ¦ or because the way Iβm measuring it (the e22 has its network attached to ground so..)
Is connected which is something
Do you have another board that you can isolate the filter on to compare?
That bandpass looks about right just the insertion loss looks hefty
Yup. I dont think its because soldering. Most likely because the e22 internal rf network
Possibly could move it bit up to allow more room
One thing that scared me one day I tried to test something, is that the live ufl is in βshortβ with ground
I mean, of course is in short from a multimeter point of view⦠is tied to ground with a coil.
So I think that the missing energy is because is scaping inside the e22. Otherwise as you said the curve is good
Do you have a bare PCB to test?
Or two sacrificial antenna cables for a suspended test?
ah yeah, I already did the test only in the filter. I was happy with the filter. Now I was testing to see if it was properly connected
cool, firm sees the radio and the gps just fine
gps works fine
the pps led does not light at all. I guess the gps is mostly sleeping, just waking up to get new position and then to sleep again
wondering if should be put at all the pps led
not complaining, the cost is ridiculous but some people may complain 'this thing does not light at all'
@olive basin remember how I said I had 2 others running perfectly? Turns out one died on me without my knowing last week. It was the one rubbing on Keith's board with the 2S LTO powering it, but I suspect something happened with the charger as it won't power off battery now
I have to go up and take it down to see what happened to it
Hotplate..
But why? Is it really a need? The filter comes with side contacts. Is as simple as to make the pads a little more big so the tip can touch both pcb and side pads just like when soldering the gps and the e22. Seems unnecessary to me
Hotplate is an asset to any DIYer..
I have one. Is faster and safer to solder it manually
If I can hotplate over soldering, I will. It's so much easier.. And I've been soldering for over 35 years..
Not risking some βachoooβ flying things
You're no supposed to sneeze on it.. LOL
And I'd never heat the full board if only doing those 2 items..
Accidents are not suppose to happen π€·ββοΈ
Yea, I just make sure they don't when the hot plate is out..
I have a big hotplate too.. 9"x9" if I remember right..
I mean big for what I use it for..
If I were to wait until have time to lock out from the accidents at home I just wouldnt have hobbies right now π
I bought it to replace the ESP32 modules on D1 Mini32 boards..
upgrading from 4MB to 16MB..
Still is faster to tip in that heating the pcb area. And also no need for extra care to not burn out when manipulating the hot pcb. I dont know, I dont see advantadges. Can be automated, can solder a lot of components at once.. but in this case for a couple of components I think Im faster with the traditional solder
@olive basin I'm seeing a lot of failures of washtastic boards in the chat. Do you know what the leading cause is/are?
Low temperature solder is an asset here. The high temp stuff remains in place, and the odd thing here or there can be made electrically sound in one pass.
And hotplate > iron 9/10
Or i did something wrong
I haven't seen many π
Afaik theres more working boards as to broken once
Considering also that ive probably made over 20 boards and I just now have 3 not working
(yet to figure out why)
Since all the pins are connected to the lora module
Can't change the promicro since I don't have any unfortunately
@olive basin any idea what's supposed to go on these pads? No reference identifier and it's the last component on the rebuild
Wish me luck. Just prepping the PM then it's the moment of truth...
Welp, i'm happy to report that i now have a WORKING 0.3.2.
Awesome
I think is a mistake of a lot of messages trying to help one person.
pps seems so be an output so the diode seems to be correctly connected. Looking at the output of the meshtastic console, it takes less than a second from hardsleep , get position and hardlseep again
User error? Trying to build a board that's ~3-4 revisions old that has since been fixed/upgraded and, in turn, resurfacing old issues that aren't really issues anymore? I mean, these two reasons are the contributing factors for me. π
i guess thats why its not on π€£ ir its not done correctly
? If tje pps is output, and is connected to the resistor, and the resistor to led positive, and led negative to ground, isnt that the correct connection?
Well as I said, the gps stays out of hardsleep model for less than a second. I guess in hardsleep the pps is not working
perhaps
I think there is not an option to not hardsleep the gps in the firm..?
π€·ββοΈ
Check the datasheet to see if it's a drain or a source.
I didn't want to say that "Ali3n is doing it on hardcore mode" is the main reason, but Β―_(γ)_/Β―
I'm more than ok saying it, or having you say it lol
A.li3n is doing it on hardcore mode. π
Checked it, that why i said that βseems to be outputβ. But the datasheet is quite shitty writen..
I was right. I commented the down() call and pps works
not leaving it as is, I dont want to drain the battery because the pps led
just wanting to test it π
hmmm... could maybe make the resistor bigger to make it dimmer
no no
I dont mean the led is going to drain the battery
the gps in full power without sleeping is what's going to drain the battery
a
the gps is good doing the hardsleep... so imho I would remove the pps led
is never going to light
i shall remove it
removing not bcause the costs, which is nothing, but because if selling these, people can and will complain that the pps led does not work
Totally
anyways it was a nice touch to include the pps π
coming to think about it, if you remove the pps my boards will become collectors edition exclusive
Why not
What if i maybe perhaps already did
It was pull down anyway π
It output voltage
Datasheet also doesn't say it need any pull ups or pulldowns
Not even the diagram has any
my daily reminder to let ppl figure things out for themselves
Yesh thatβs why I called the datasheet shitty
But it worked when it had a "pulldown"
i'm reviewing the documentation. may be endevoring to build a 4.0 board.
anyone who has built one had any issues? gotchas?
On the first iteration there were some issues but not on the newest afaik
@viral pier got the first one and then was it @finite palm? Who got the latest version
U just gotta remember u need to flash the bootloader onto the nrf52 chip
U can't do that with usb
was this board built in KICAD? i'm at work on my tablet so forgive me i haven't unpacked the entire github repo π
U need swd programmer
Easyeda and ive only published the files u need to order everything
No project files
perfect
thanks π
looks like JLCPCB is the pcb house of choice. ive used them alot before so should be good.
on the solar IC is the power input wattage documented? how big of a panel will it support? sorry for 20 questions.
i'll look over the documentation i may be able to answer most of my own questions π
this project is something i'm very interested in. NRF+1watt ++ Solar is very desierable ! gereat job @olive basin β€οΈ
No clue rly, max voltage is 28 and max charging speed is 2A tho is should probably reduce that
probably plenty for most of the smaller solar panels that we will be using.
Oh yea
Just reminder again u need a swd program to flash the bootloader on promicro
For example j-link
Or u could make a esp32 into a flasher like i did
understood
i'll ensure i have the required equipment. i have a ton of Wiimos D1 mini's lying around. might use that or just pick up a SWD. they aren't expensive. i think i had one but accidently flashed it into something else LOL.
was building slimeVR sensors. gave up. now i have a BUNCH of D1's lying around not being used π
Hmm I thought they were esp2 boards. π€
*goes and checks
Nope esp8266 board.
I'll just get the flasher π
ok so working on dumping files into JLCPCB and things are kinda working for the most part. some of the parts are showing missing or not matched :/
i mean i could hand solder this stuff but was going to see how much it was for JLCPCB to do the assembly
them or PCBWAY
You should be able to match everything with a quick search
understood i'm just now poking around with it
π¬ i think for over 200$ and not all the components are even going to be placed i'll just diy this thing xD more fun to buy a hot plate anyway
for anyone who manufactured the v4 board. did you smd solder yourself or did you have that done for you?
yeah i saw that it was a underneath ball grid chip
i think with a hot plate it wont be too bad but yeah might still be beyond me :/
still working through the BOM. kinda hit or miss on JLCPCB and LCSC
but searching it out mostly. and the part/footprint numbers being R or C are typically Resistors and Capacitors so that helps narrow the search
Does anyone knows how the E22 behaves? Is the PA inside always powered even if the sx1262 radio is not transmitting?
Iβm having a hardtine testing my first washtastic board which went to roof yesterday. Coverage seems very bad. I tested thing on the desk without antenna attached because meshtastic had no region configured and hence should not be transmiting. But come think about the PA and dont know if is always powered.
Could be that the PA is fried
I think it's only powered when txen goes high
There's a lot of debate about whether MCU control is better, because you can ramp it better, but RadioLib has a longer delay iirc...
Is it worse on tx or Rx?
Tx
Rx seems as good as always
The shitty datasheet says that tx_en controls the rf switch but does not say anything about the pa
So could it be that even if the sx1262 is not transmitting, the pa is pushing its 7dBm anyways?
But then again if the pa is always pushing, wouldnt it fry itself anyways if the rf switch is mostly in rx mode?
Maybe the e22 is not fried at all and I should check the conections of the cavity filter and antenna π€·ββοΈ
π€·ββοΈ
what if u try connecting antenna to onboard ipex of the e22
also a power meter would help
The board is a washtastic 0.3.5.4, not the one with ceramic filter but the one with cavity filter.
Is already directly to the e22 ipex
oh that
Should buy a tinysa..
i do want a meter cuz why not
I want [insert here] because why not
XD
What resistors did you put in the washtastic for the voltage meter? Do you know by chance the proper adc value?
I guess the resistors are the same in both 0.3.5.4 and 0.3.6
1.685
New resistors to make it work out of the box, as per comments in the variant.h
// Voltage divider value => 1.5M + 1M voltage divider on VBAT = (1.5M / (1M + 1.5M))
thats what i just changed em
tho not sure which way lol
Yeah I also wonder which goes to positive and which to negative
Makes sense to put the higher value to ground
Much better
Seems like i forgot to change the pcb color π
Oh well
First 20 will be green lol
Nice. I see you included the bme
Didn't cost me extra so ye
Awww no 7.5v option
then u choose 6V :)
What MPPT chip you using ?
cn3791
Ya, I think 7.5v needs a custom resistor value. 6v pulls too low
Itβs that 3w MiniRenogy panel. Itβs such a perfect panel otherwise yet has such an awkward voltage π€£
i'm using that panel on this board
Oh snap. And it works well?
yup
Well look at you being awesome.
battery has been full ever since it was installed π
cuz it has good sky access
my other node not so fortunate
it died π
RIP
When I was 3, I was nearly Me
so idk what im gonna do with it π
Is it (900M33S) still working for you? I was planning on building something with it, but got sidetracked. I have 4 of them in my project box. π
Sadly, when on battery it would lock up during Tx without warning, so I had to go back to the M30.
π’ Oh well....
They just sit here... Very sad.
I only run M33's on Wehoopers 2W HAT now. I'm sure other boards can handle it, but I don't have much use for it outside of a static node, so the Pi's offer the most reliable solution.
You can run the M33 on the Washtastic, no question. You just need to drop your max power to like 3-5 (vs 8). But then again, nobodys running a M33 to have it run sub-1W lol
indeed!
I have an M30 washtastic as my mobile node right now. Its actually doing really well.
I'm trying to find that HAT. That's what I was going to build... I bought these back before prices went up.
interesting, the 5V converter should be able to deliver upto 2.4A buuttt π
guess not lol
or voltage drops
i was running on a 0.3.0, dunno if you changed components since then.
that could also explain
ooohh
yeaaaa
i have
Good luck with it, if you're doing PCBA you'll be fine. But if you're like me and you're allergic to PCBA, then you're in for a project...
I will say @olive basin has always been VERY good about making their boards easy to read/understand.
Hoopers was like trying to crack a cipher...
now using TPS61230ARNSR instead of MT3608
tho i think the biggest thing on 0.3 was the layout
it was horrible
At this point, I'd rather not reinvent the wheel if someone else already has a design.
u should update the case to fit the never one haha
Look closely and tell me whats missing here (aside from actual components)
you mean an 0.4? I haven't reached the point in my life where I hate myself that much to inflict that much pain.
v0.3.5
i actually should have taken a picture of it for the projects thread, didn't occur to me.
i don't mind buying new boards, its the new components that's been killing me with these f'ing tarrifs.
Tom helped me finally fix my ME25's power issue, so i've been meaning to put in a new order. I'll throw some 0.3.5's on to have for when i get around to putting in a new LCSC order.
https://www.elecrow.com/store/valzzu
Elecrow will also be selling them eventually when manufacturing finishes
I just went to the Elecrow site and saw the ThinkNode M1, it initially showed a $37.50 price then when the page finally loaded (and it likely did the GeoIP lookup), it shot up to $53.90 hahhaha
would u look at that
beautiful
I just found by looking at your picture, the bluetooth antena has traces resembling a coil
I still have 10 boards... 5 with gps and filter and 5 like the one you showed, but without the BME280
these days I have been having fun with a carputer
finally pulled the trigger and got another new toy
nice
@olive basin Any ideas on what would need to be changed to make this support a 33 radio ?
I'm fairly certain 03.5 can support it.
The boost converter is better plus the layout is way better than the old version
U could try drawing like 1.2A from it to see
How thick are your traces? You can use more than 1 via
.5mm iirc
5v rail
Lemme check
.75mm xd
added few more vias on power lines
but yea, only one way to find out if it can supply enough current to not die π€£
If I can buy one before they sell out, I'll try the 33 radio on it. It's all I've got! π
You in the US ? I'd be willing to split an order of 5 PCBAs...
I am!
Iβd be down for a group buy too
@wary yoke @deep tiger How many do you guys want to get ?
Are you getting the 33db?
The pictures of the pcb show pads on the back for a gps, but I don't see which gps chips are supported π€
all i know that most work π thats what ive read
Fair, just checking... not that I need a gps anyways π
for sure i know ATGM336H works xd
When do tariffs get loaded on elecrowβ¦ Iβm seeing $85+9 shipping to USA
Tariffs get charged at your end, I think.
Well, the importer pays.
Which is probably fedex
Who charge you.
It depends.. they can be prepaid or postpaid.. most of the purchases I've made have been prepaid. For example.. my costs of ordering PCBs from JLCPCB has basically doubled from six to eight months ago for the same PCBs
With them they charge it up front and provide it to the company handling import / customs.. whatever shipper it is
I could probably google this π«£ but if anyone knows off hand that would be helpful - whatβs a guess on how much those run lately
55%
It almost made me resort to domestic production of some PCBs.. then the lowest domestic quote I got was $408 compared to JLCPCB's $126 even with the tariffs
Well dang.
I ran a quote through JLCPCB for Qty 5 of the Washtastic boards last week. Using the 0.3.5 version with assembly ( without the pro micro nrf module) came out to about $340 with all tariffs and shipping.
The worst part is when you have to pay for additional processes like flying wire tests or x-ray inspection, etc... most of the chinese manufacturers like JLC are adding that onto the cost of the production and making it subject to the tariff also.
To me.. those are services they've performed for us and should be paid separately so the tariff doesn't apply. It isn't something they're shipping to you as a product. The tariff SHOULD only apply to the actual physical product costs... but it's impossible to explain that to the customer service reps
Sorry, I'm kinda sidetracking this self-promotion thread with non-washtastic conversation.. my bad
Yeah they even provide a chart explaining what process or component falls under different tariff rates, but then just do a flat 55% on total from what I could tell.
woah! that's more than double for what costs to me the same 5 boards. I'm seeing $158 for x5 v0.3.5 fully assembled (but the promicro) and shipped, tax included and without coupons.
Merkins have that 55% tariff, but iirc they've lost the cheap shipping rates, too. Presumably that's because they rely on a volume discount which doesn't exist anymore.
Worth noting that, at least for the UK, orders under Β£125 are deminimis-ish exempt from duties, whereas over that need to either use a DDP carrier like DHL, or risk a bill when they do arrive.
So there's a wobbly bit in the net-cost line around there, and I try to keep all my orders under 130$/100Β£ for that reason
Iris getting her design listed as singles from Elecrow is really good from that perspective: group buys might be hit by a duty charge, and go over the limit, but with singles it's potentially cheaper per unit because they skip various things.
Through JLCPCB? Mine was like $200 when it was just in my cart. I didn't see the full picture until I went to go checkout.
yes. I just went full order just to be sure before typing my previous message.
for the record, this was what a 0.3.5 cost me 1st july without the E22 module (I already had them from aliexpress)
I guess is because I'm located at EU.
I would love to see the costs breakdown in a USA order
I've sold 5/20 π
I don't get paid until the 29th π
I don't think they Will be sold out before that
gotta raise prices on elecrow π but after this first batch of 20 π
usd values is lower than euro sooo yea
It looks like you did not have the BME280 on your build which forces standard PCBA for me. Also adds about $15 to the total for the BME module.
ah yes, that's true
I did try out to add the bme back then and yes, saw how costs went up because switching to standard pcba
$15 was the least cost, thats the total for the 5 units
@olive basin did you stop selling on etsy?
Just ran out of boards
Before shipping and tariffs.
I might run the no BME version to see what it would cost
yeah... this is why I ordered without BME280, and added them by buying them at aliexpress then manually wiring them to the washtastic board.
No BME brought it to like $250 with shipping and tariffs
one should ask, what means confirmed
maybe shipped, maybe received by the customer.. ?
I understand that 'salable' are already manufactured and in stock ready to ship
they are manufactured but still in testing π tbh idk why they even listed them xd
yeah, if they are not in stock because they are being tested, they should not be listed as salable
mhm
π
Rip
yup... I looked that board was 'working' because it did theradio init
but when tries to tx does that
I just soldered a second board and is doing the SAME
i can not believe it
multimeter says I still know how to soldering
I have just continued from that message. I have not ordered any Washtastic boards yet though. I did have similar warning ordering femtofox CE boards and they work. I think @olive basin has a simple guide on one of their other boards that tells you to just click continue.
Guide for ordering Mesh-Tab: https://github.com/valzzu/Mesh-Tab/blob/main/PCBs/Mesh-Tab/Ordering.md
Yup, just click continue
The tension voltage divider is the same in the washtastic v0.3.5 and the version with gps and band pass filter?
Should be iirc
Will check against the files just to be sure
I got up to the roof and changed washtastic board 0.3.5.4 for the 0.3.6 gps and noticed a small drift in the voltage reporting. The adc value was properly set 1.685
On another note, time fix is driving me nuts
These are the reporting for device, environment and gps
Is fixing time somewere in 2019
thats something i cant do anything about π
I know this is not a specific bug of the board
Is software related but commenting here if someone knows whats happening
confirmed, they are the same
from the 0.3.5 board .csv:
15 1M R6 R0402 1 0402WGF1004TCE UNI-ROYAL(εε£°) LCSC C26083 0.001
16 330kΞ© R7,R8 R0603 2 0603WAF3303T5E UNI-ROYAL(εε£°) LCSC C23137 0.001
from the 0.3.6 filter and gps board
"23" "1M" "R6" "R0402" "1" "0402WGF1004TCE" "UNI-ROYAL(εε£°)" "LCSC" "C26083" "0.001"
"24" "330kΞ©" "R7,R8" "R0603" "2" "0603WAF3303T5E" "UNI-ROYAL(εε£°)" "LCSC" "C23137" "0.001"
This is driving me nuts. None of these boards works (i still have boards to test) they all recognize the radio sx1262 and init it properly but all of them fail to tx with busytx error.
tf
One of the washtastic boards, the left one, has pins soldered to board but not to promicro. I tested 4 promicros and all them gave me the same busytx
can it rly be that the lora is dead?
On all the 4 ones?
Check the pro-micro doesn't have any loose strands of ground plane on the edges.
Check the E22 doesn't have any shorts under it.
the radio modules were hand soldered, not uising paste and hotplate. they cant have shorts
i have 3 also that doent work so yea. if u get them working maybe i have the same issue on them
the promicros were also hand soldered
but still, I get the error con 4 manually pressed promicros on a board that has the pins soldered
so how come they all recognize and init the radio properly, but none can transmit ?
what's the meaning of busytx error ?
Usually busy or IRQ line
Yeah, no. Try again π
Try checking for shorts pin to pin and end to end.
Also worth giving it all a squirt of flux and reheating.
i think my issue is promicros fault since i changed the lora module on one and still didnt work
This board had the radio soldered by hotplate and paste. I just manually soldered pins rows and pushed by pressure the promicro. Is also giving me busytx
I've heard people file the promicro to turn it into a castellated board.
Is the Rxen pin connected?
rx en is on the other side π
really? shit
welkl that would explain the manually testing
then.. do I have 3 fully soldered not working boards with the same error ??
Check for loose flakes of ground plane on the edge of the promicros
Check using for shorts using a high ohm meter
Check continuity using a low ohm meter.
I dont get what a βloose flakeβ stands for
Like the fibreglass fibres, with bits of ground plane on them
I can't find the picture.
#1194757507013427250 message
Bare ground plane on the edge.
I'm out of ideas
I dont have proffesional tools, just a standard polymeter
multimeter
in continuity mode all the pins of the promicro gives proper contact to the ones at the radio module
no obvious shorts between them
you are not going to believe this
the boards I was testing before soldering were indeed not working because missing the rx_en (silly silly karman that wanted to test for bad promicros and did it wrong)
but the 3 boards I had already soldered and were giving the same txBusy error... i got them working
they needed the battery
Don't hask me how or why... interference of the always switching lipo charger? not enought power from usb host?
but plugging the battery solved the infinite busy tx
yeah, the promicros are popular at failing.. that's why I wanted to test them before soldering
What I couldnt foresee was that the missing battery would trigger such failure
gotta make a promicro testing board π
hmmmmm...
and then custom firmware to light all the leds xd
maybe is sequence
π’
in any case, there must be some kind of combo with the washtastic board
maybe with the 5v buck
I have 2 faketecs and tested wiuth them, no problem without the battery
i think it is the 5V boost
and the lora module trying to tx
promicro cant supply enough current most likely
idk
something fails anyway
maybe the 5v buck is too close to the radio
could it be given that tx wants 500mW by default
come to hink about it, the promicro doesnt have a usb 5v out as the xiao has
Need to add a capacitor on the battery pins.
there is
How big π
I recall seeing something on the ti forums about running something like this without the battery connected, and they basically said "use a honking great big one"
That's the 1206 100uf 6.3v one
?
yea, that was mainly to reduce the ripple current
those 3
no clue if the pogos are the correct size tho π
π
That's the real reason designers just chuck 3 caps at everything.
I was joking...
Just tell people to use it with a battery attached
Pretty sure @meager spruce already said something similar.
ill have to do that π
- Power cycle it.
No? - Reheat the solder joints on the headers.
Still nothing? - Did you try connecting a battery to it?
Those 3 steps tend to cure most Meshtastic DIY project headaches
haha yea
what components are 27E ?
Oh, you're making a nail bed?
You sure there's not a 12 pin pogo clip somewhere for cheaper?
gotta see those boards
I recall having seen a picture of a power test to the e22-900m30s showing full power but cant find it
The hackaday post?
I though I had seen some pictures here
gotta find em
thanks!
also adding this
The CDEBYTE E22-900M30S LoRa gateway used in the Femtofox pro consists of 22dBm SX1262 FM Modulator IC, + a 8dBm nominal amplfiier, giving something like 30dBm TX power, theoretically... The actual TX power is highly voltage-dependent, and deviates signficantly from the values listed in the datasheet. I investigated that, and plotted the nominal...
Somehow my washtastic board drained by battery all the way down to 0v
The voltage divider was also bugging out
reheheheh
Ahh
On the 0.3.0/0.3.2 boards, whats the minimum Voltage for the solar port? feeding it 3.97 and it's not booting. Didn't look like it was getting power from the multmeter. It powers up fine from usb-in on the PM. Wondering if something could have gotten cooked on the PCB...
Thats feeding the CN3791 directly, right?
I think it needs to be 4.5v
I ended up just plugging right into the usbc of the pro micro for my solar panel
your solar panel has a 5v output regulator ?
Yeah
Itβs a 5w Soshine panel
Anyone happen to know how long elecrow take to ship? Ordered a washtastic node on 22/08 and it's still displaying processing, no word on shipping, and payment has definitely been taken
fucking elecrow
ill go bug em about it
i did also spend money on the boards to be produced so u are sure i want them to send em π
They seem to still have issues in testing the boards
idk why they even listed them as in stock
Didn't you say they needed a battery to start up properly?
aparently that wasnt the issue
at this point im leaning against something not connected properly
they did offer to send me samples to test etc
might have to do that
lawl, thats the typical error when the promicro is faulty
no capable of finding the sx1262
wait
just make sure that you gave them the proper firmware
if they are trying the wrong one, the pin definitions wont match the sx1262
the firmware initialization probes for several radio modules, as you see in the pasted log, and when doesn't find any then falls to error -3
but is weird.. are they getting this error on all the manufactured boards o just one ?
good question, will have to ask that too
the battery thing happens when trying to tx in usb power. Radio init happens happily
and tx doesnt happen if you do not choose the lora region
okay it seems to be on all of the boards π€
