Desk of Ladyada - DS2484 Testing & Round Touch Screen Samples https://youtu.be/MUO_OD5AN08

Ladyada tests electronics like CH9328 and HX711, while also developing a DS2484 breakout for easier I2C sensor connection on SBCs without GPIO. Also featured are new round touchscreens and a RP2040 Feather Adalogger. Plus, a quick dive into 1-Wire interface chips.

[nova totem]

Quick question have you ever dealt with a sensor that is shared wire SPI (shared MOSI/MISO?).

[open girder]

yah! as long as they have the same voltage level and separate select lines, should be fine!

[shell mason]

pixel your trinkey

[strange mantle]

STEMMA QT (for I2C things):
https://learn.adafruit.com/introducing-adafruit-stemma-qt/what-is-stemma-qt

[cinder wind]

It's not StemmaQT though, it's a 3-pin (3.3V, Gnd, D4) for hooking up a button or other sensor

[split gazelle]

https://www.adafruit.com/product/5755

[strange mantle]

oh! nvm.

[flat girder]

Several years ago, I did a couple of "wearable" projects with NeoPixels. Quickly discovered they're TOO BRIGHT in a lot of situations, so used PID 1384 -- now discontinued. Would have worked well with this!

[cinder wind]

I though it was StemmaQT too, since many other Trinkeys have a Stemma port

[strange mantle]

good catch!

[strange mantle]

yah, that's what threw me 🙂

[cinder wind]

(and if anyone cares, the three gold pads on the back are the SWD programming pins if you want to hook up a SWD programmer. I think they use this for testing)

[unreal bay]

What pixel ring is recommended for webcam and this? I have one of those reflective screens that can use any color lighting I'd like to play with.

[unreal bay]

lol the freezeframe on youtube is gold

[haughty quiver]

thanks for keeping me honest @cinder wind !

[waxen bough]

would this be good?
https://www.adafruit.com/product/1586

[strange mantle]

hey i thought it was stemma too 🤦‍♂️

[haughty quiver]

yes, that'll work great @waxen bough but you'll need to solder on your own wires

some strips like these https://www.adafruit.com/product/1376 have wires already on that can be connected to the terminal blocks

[waxen bough]

There are so many choices on adafruit. Soldering's okay.

Are strips just as good for webcam lighting (aside from the fact you could roll it in a ring...) Perhaps two separate parallel strips to reduce shadow.

[haughty quiver]

that's a good idea

some diffusion helps too

[waxen bough]

warm white/ natural white / cool white... ugh another choice to make...

[cinder wind]

for webcam on faces, stay away from cool white. "natural white" is basically daytime white and "warm white" is sorta like evening colors, more orangey and usually pretty pleasant on skin

Nice, @haughty quiver !

What’s your rough guess on possible cable length, @haughty quiver ?

[haughty quiver]

[haughty quiver]

ooh good question, I suspect a 3m TRRS cable would work fine, I'll try some things out tomorrow on the show

[gray obsidian]

@nova totem is that experiment related to your weather station in any way? I know you've been working on that lately with the cups anememeter.

[open surge]

Awesome projects everyone, thanks for sharing

[nova totem]

It is! A lot of basic stations use various resistors to detect the wind direction from the vane. I saw an idea to use a magnetic rotary encoder. Last week trying out the TLV chip and this week this MLX one

[tulip canyon]

"You don't need a weatherman to know which way the wind blows" you need the MLX90136 - Bob Dylan probably

[sand lotus]

Very cool, unique approach.

[nova totem]

The weather vane itself it still a work in progress in fusion 360

[sand lotus]

With the warmer weather here they're predicting a higher than normal hurricane season. I'd still like to make one with a strain gauge rated for like hundreds of mph wind.

too many projects never enough time.

Which micro-SD breakout card would be best for a Feather M0? Performance is not a critical requirement. #254 or #4682?

[drowsy shoal]

i use #4682 with a feather nrf42840 (3.3v logic) because i don't plan on using it with a 5v logic device. also easier to power because 5v for #254 may not be available if using a lipo battery

[cinder wind]

we have an "ablative joystick" for our PS5 here at home. I need to replace the right joystick that's failed

[sand lotus]

[sand lotus]

modules aka libraries

interesting, honestly didn't know you could do that.

i've always gone to RTD, that's actually really helpful.

[shell mason]

learning and being curious is human nature thing

[inner spade]

Can you drill down in help like help(math.sin)

[lavish patrol]

Good idea

[sand lotus]

i feel like that should be in the circuit python essentials learn guide. would have loved to have learned that one a long time ago.

looks like it has to be a main class and not a function of the class

TRRS jack hiding in the usb?

yep

[lavish patrol]

🤔

[sand lotus]

i've never seen that, very odd and cool.

[cinder wind]

The dir(board) type stuff is nice because it returns a Python list, unlike help(board), so you can do things like... find all analog pins:

>>> import board
>>> analog_pins = list(filter( lambda x: x.startswith('A'), dir(board)))
>>> analog_pins
['A0', 'A1', 'A2', 'A3', 'A4', 'A5']

[sand lotus]

anything that uses lambda i doubt will be beginner friendly.

do you have that one in your tips & tricks? looks like something good to have around.

[cinder wind]

ahaha ikr? I always have to look up how to use it. "lambda" is just how Python does one-line functions, but it seems so cumbersome

[cinder wind]

I don't think so, I'll see if I can add a version that's a bit less daunting

[open surge]

Bah, we all just copy and paste your tips and tricks anyway. 🙂

[sand lotus]

looks like most i'm seeing are for USB or TRRS sound adapters.

[cinder wind]

ahaaha thanks! I'm always copy-n-pasting from it too, because I still can't remember how to do digitalio

[sand lotus]

plt = plantronics?

[lyric frost]

@haughty quiver I think you mentioned wanting to find a WebMIDI drum synth site? Is this what you had in mind: https://samblenny.github.io/web-midi-drumkit/ ? I just threw it together last night, so it's definitely beta. But, it seems to mostly work?

[haughty quiver]

@still bane oh wow! I’ll try it out, thanks

[still bane]

I'm not super happy with the samples, but for CC0 on short notice, they're pretty okay. It would be easy to fork the repo and swap out the sample files if you were so inclined.

[haughty quiver]

@still bane this works great! Is it ok if i link to it and credit you in the learn guide for the drum sequencer?

[still bane]

@haughty quiver yeah, sure.

[timid plover]

Thinking about the deep dive w/Scott - some questions/topics 🙂
while looking for arm toolchains, I notice a tannewt had a github action for the gnu toolchain - how did a particular version get chosen - and installed - did you build from source, or select from a distribution?

now that @rapid hornet is pursuing clang support is that installed as a github action
( ok - I know little about github actions anyway )

How did you choose the version of those tools to
a) work with on your personal devices, and
b) what tradeoffs are considered for general use in CP development

Will recent changes to embedded and StemmaG0-Template be considered

how do CP builds deal with PATH order - to ensure the 'right' tools are selected?

[brazen grove]

gruetzi

I gave up, it all looks correct on the logic analyzer, and it worked on rp2040, i'm out of ideas.

[timid plover]

the timecodes on youtube are showing negative numbers - maybe something changed on youtube?

[sand lotus]

interesting, yeah it does

[timid plover]

or maybe I never notice the minus sign

[sand lotus]

hello, it's 92F here. sweating while sitting in the workshop watching your stream.

[timid plover]

I'll take the absolute value 🙂

should be an interesting dive - great topics

[sand lotus]

I haven't been watching many streams lately, missed some stuff about the language model you're working on, that sounds different.

[timid plover]

I think you forked someone's repo

[sand lotus]

I've yet to use co-pilot, unsure how to even do that.

[timid plover]

yes - I was searching for arm-none-eabi-gcc

[shell mason]

there is ai kit for raspberry pi

https://www.raspberrypi.com/products/ai-kit/

[sand lotus]

Makes sense, thank you.

[timid plover]

so anyone that uses your github action CI gets the same binary ?
yes it answered questions

[shell mason]

djdevon this could show some https://youtu.be/HgIMJbN0DS0?si=jdAfU8rl5o5Gvs5u

the pimoroni m2 could help for that pile

[timid plover]

I was going to ask how to coordinate the graph to locations in the code

[timid plover]

good to see the Nordic PPK at work

I didn't realize it had logic analysis support
( You've had an interest in sigrok type loggers in the past - any progress on that front Scott? )

seems like auto connect could be a configuration option ( when going to sleep )

does the app integrate the power over time ( is that the average? )

[timid plover]

was the blink on the same pin as the boot button - did you change configuration of the gpio ?

[brazen quail]

Pronounced "Kewlombs".

[old surge]

Gesundheit

If I could ask more of a general question: any advice for beginning a debugging/development setup (programs/IDEs/cables), sort of early steps beyond including print statements?

[brazen quail]

Thank you Scott.

[timid plover]

I was going to ask about creating python helpers for customized gdb debugging CP

[old surge]

Thank you for your response! Your answer to dcd's question overlapped with mine as well. Cheers!

Maybe it's so another file/method can use the digitalio pin too without passing the reference about and without knowledge of the other code (and the dreaded pin already initialised error)

Definitely feels like it would be significant with the keypad reinit, but maybe not (quick enough to catch a bouncing key)

?Question, is there a way to connect a BT keyboard/mouse to 2 different RPi's? I would like to switch between the Pi's rather than remove and the pair the keyboard each time I want to switch between them. Is there anything?

Follow-up from last week's parsec: you can create the help message for your class/function/method by adding a comment immediately after the 'def' line. Thought I'd throw that out there.

[cinder wind]

Here's a quick CircuitPython tip that I've been wanting to use:
There's a new way (well new to me) to tell what kind of board you're on: board.board_id.

[lavish patrol]

Set phasers to distortion.

The code is up - text is waiting for embedding & tweaking

[cinder wind]

Wait, who is Ecks Bachs?

[lavish patrol]

Lol

[pearl shoal]

BTW, your hardware is a super example of how to use the XAC well -

Start with the Joystick as a controller using XAC and then reprogram the TRRS to be a mouse input with the same joystick

So you can transfer the practice they get gaming into their practical PC usage

[lavish patrol]

@cinder wind He's Johann Sebastian's brother...

[pearl shoal]

You can send buttons in via the USB as well

[cinder wind]

nice

[shell mason]

the trinkeys are great for it

[pearl shoal]

The code is there

Page is not

Here is the mouse demo https://github.com/adafruit/Adafruit_Learning_System_Guides/tree/main/TRRS_Trinkey_Demos/CircuitPython_Analog_Mouse

It will work with @haughty quiver's hardware

It's PIO-based (so bit-bang but very fast)

[inner spade]

The “dog house” USB connector

[cinder wind]

USB-B is great for instruments because it's a really strong connector. USB Micro-B is so fragile. I've destroyed a few instruments with their tiny micro-B jacks

[lavish patrol]

Dog house...

[haughty quiver]

https://github.com/rppicomidi/EZ_USB_MIDI_HOST/tree/main

[pearl shoal]

A quick reminder on the USB Host Feather - the PIO-based USB Host uses the PIOs, so NeoPixels won't work (or, if you enable them first, the USB Host won't work).

NeoPixels on the RP2040 also uses PIO state machines

[shell mason]

lars usb host platform

[pearl shoal]

Sound is good

[dusk socket]

yes

[lavish patrol]

It's a bit loud.

[shell mason]

this could be fancy with neopixels

[cinder wind]

now play Axel F from Beverly Hills Cop!

[pearl shoal]

So, the CZ-01 is a host for the AKAI

Output is straight out from the CZ01 to the amp

I was waiting for it to hit a PC/Mac somewhere

[shell mason]

the feathers control thigns

[pearl shoal]

So the CZ01 is a MIDI host, not a USB host

[lavish patrol]

Getting a "Close Encouters" vibe here...

[shell mason]

https://tenor.com/view/hand-lights-pass-on-carry-on-pass-the-light-gif-17173743

[pearl shoal]

Fair enough - you're sending from the Akai through the USB Host to the MIDI "in" of the CZ01

"The More You Know" theme?

https://tenor.com/view/the-more-you-know-gif-26317296

@haughty quiver - I have a charity recipient that really wants to drum again - I might very well pick your brain

[lavish patrol]

Camera died, @haughty quiver

👍

[pearl shoal]

@haughty quiver do you think the TRRS Trinkey can send/receive MIDI directly?

I don't know enough about the voltage/speed/signals (analog/digital etc)

[shell mason]

magic is there

[pearl shoal]

Pretty good organ

[cinder wind]

without additional circuitry, the TRRS Trinkey cannot do classic/serial MIDI

[pearl shoal]

Ok @cinder wind - is it 5V? analog?

[cinder wind]

no it's a current loop, but digital UART. So on MIDI output you need a current-limiting resistor and on the input you need an optoisolator

[pearl shoal]

The caveat on not using USB Host + NeoPixel on that RP2040 is probably worth mentioning

It fails silently

[lavish patrol]

Thanks, @haughty quiver 👍

[lyric frost]

Bye all. 👋

[haughty quiver]

[hasty loom]

JP - Blast from the past. I've had this since the 80's or something! It sat unused for 30 years or so until I got a Midi Featherwing and started playing with it.
Thanks for the video! and I'm gonna try to duplicate your setup. I have a very simple MidiPlus controller which does have arpeggiator.

[haughty quiver]

@hasty loom ah no way, CZ-101 !

that's excellent, have fun! I'll try to get the Arduino code I'm using committed to Learn Guide repo today

[unreal bay]

Hey Tim 👋 Exciting BLE times, or will this be the "Bleak why you hurt me so" stream...
Doubt I'll be much help, only starting to touch the surface of the adafruit BLE characteristics

The android and iOS app code (github) was useful reference for some of my playing, also the Bluetooth Web Dashboard learn guide and github repo has some JS code interacting with some of the nrf services rather than the adafruit services like file transfer and circuitpython service.
The NRF Connect mobile app is a life saver for knowing if things are broadcasting expected services

made by nordic

[left ember]

eyy this is cool, i did a ble with circuitpython on rp2040 last year

felt like there wasn't much documentation

i like the lightblue app

i don't think there was a library last year, i had to connect to it via uart

so is the cache discovery error because it's looking for a previous connection?

or looking for a cache that would containt a previous connection

[untold frost]

Watching youTube and there is chat there too.

I'm looking to get a ESP or RPI2040 based board from AdaFruit and experiment with MQTT, any one have experience with that?

We are the same, Steve B and BitBanger is one and same.

[unreal bay]

remove the CPY bluetooth devices from list, maybe the paired state isn't helping, or maybe the python side needs to also ask to pair immediately after connecting (pretty sure some web code did that)

[left ember]

so are you trying to reach a circuitpython device from your machine or vice versa?

[unreal bay]

interesting, now try later version

oh thought was bleak error not bleIO

[unreal bay]

yes, reach CPY device from linux pc

holy moly, that sounds like progress. Now just nick the adafruit uuid's (no idea)

ADAF about 3 paragraphs down

[rigid crag]

you being willing to flounder in public is a huge public resource, as you are now helping more people avoid these issues

[unreal bay]

It may fail to pair a second time, unpair it first from list (remove device). There should be a check if it's already known + bonded/paired

[left ember]

can you just have your device print its own uuid

[unreal bay]

uhoh, hello world just printed 😄

[untold frost]

Easy to use as end user (BLE) means developing for it is super-complex. I had a similar experince developing for USB 15 years ago on MPU.

[grand tusk]

Someday I will connect my LED Glasses controller to my tablet using BLE.

[unreal bay]

/cp/devices.json and maybe version.json or device i think

[unreal bay]

I love the find in all files shortcut in vscode, Ctrl + Shift + F, heavily overused

[old surge]

Who needs AI? Just code whilst live streaming 😎

[rigid crag]

could that be trying to keep the meager/small device buffer empty while putting into a larger buffer on the computer?

[unreal bay]

https://github.com/adafruit/ble-file-transfer-js

Transfer UUID must be the FileTransferService, accessed by a FileTransferClient

[rigid crag]

UINT32 is the size of a Python int - so you can convert using int() -- well assuming that the bytes are in the proper order

[unreal bay]

sounds like this is being retitled the stream of BLE victory, mixed with a dash of indescision

try the existing FileTransferService if you can, but I've only been loosely paying attention last few mins

also not sure i tested BLE workflow properly (may have seen it get stuck too - esp though) ( https://code.circuitpython.org )

oh ble gets reset as the vm reboots

so TX/RX ble service dies

curious ctrl-c does too

[wraith turret]

What ide is that?

[unreal bay]

pycharm I believe.

[old surge]

Is that the most popular amongst the kind folks at Adafruit Industries?

[unreal bay]

Thanks Tim, interesting as always

https://youtu.be/FDbl3M8huwE

Tested the RP2040 Adalogger Feather and are now working on its tester. We're troubleshooting the Floppsy interface due to incompatible floppy drives. Progress continues on the ESP32-C6 Feather with TFT functionality checks. Additionally, we designed an IR transceiver, updated the HUSB238 Type C PD, and two RS-232 level shifters. We also revisited RS-232 transceivers, crucial in pre-USB communication.

some keys don't get sent in modes 0-2, mode 3 is the best mode for having access to all keys, but it requires the library in CP or arduino

some old monitor connectors?

was those too RS232?

Hey Y'll

[nova totem]

Evening everyone

[cinder wind]

Need a _zig.move_every() method

[tulip canyon]

x10 home automation seems to be having a revival

[robust horizon]

I'm headed out for the evening but here's the link for that branch: https://github.com/adafruit/circuitpython/compare/main...jepler:zigbee-prototype?expand=1

@tulip canyon you laugh but I think that stuff worked pretty well within its limitations

or maybe you're not laughing and I'm just imputing that to you

[gray obsidian]

good old reliable tech!

[unreal bay]

sure you'll be running asterisk soon, personal PBX for the win?

[gray obsidian]

Hayes!

[nova totem]

2400 seemed so fast compared to 300 and even 1200

[gray obsidian]

Paul Rickards does some stuff with those still I think

[tulip canyon]

Agreed, it's been around so long and yet really seems to keep popping up lately.

[nova totem]

I was just thinking about Kermit

[cinder wind]

Speedtest on my phone just gave me 32,500,000 baud but 2400 baud is still my favorite

[unborn patio]

Most of us don't have landlines any longer, but can we emulate the audio of a baud communication in a digital voice mobile phone?

[gray obsidian]

Sure @spring heath knows about that ^

[unborn patio]

I think Twilio could work for that

[nova totem]

It depends a lot on the hardware supporting the mobile phone. A lot ran (20 years ago) at 19.6Kb/sec max for voice, so the maximum baud you could get over a mobile phone was that

Versus landlines that were truly analog

[gusty orbit]

Fairy certainly the Arduino adaptation could be nice

[unborn patio]

How might we emulate a landline over digital?

lol what am I talking about!!!

[tulip canyon]

ThanKs all

[upbeat coral]

Thanks to all for sharing

Wow this is interesting... Thank you for sharing!

[tulip kestrel]

hay @adafruit you forgot to answer my questions last week.

Question 1: have you ever worked with a "5 Plus (16GB, 8GB, 4GB) Rockchip RK3588 8 Core 64 Bit Single Board Computer, 2.4GHz Frequency 8K Video Decoding Open Source Development Board Run Orange Pi OS, Android, Debian, Ubuntu (OPi 5 Plus (16G, 8G, 4G))"?
you should stock this two.

Question 2: if so how would you use the HDMI in?

Question 3: can you make something like the Pimoroni Unicorn HAT HD 16x16 pixel but with buttons on top, like the pimoroni button doohickey for raspberry pi. 5 should be good and should be connected via i2c the buttons that is.

[tiny grove]

I mean... it's still a "real" modem. It's just that it is modulating/demodulating WiFi.

[desert orbit]

the hx711 was the only cheap strain gauge adc i could find years and years ago, kind of a classic 🙂 glad to see a great board for it now!

[dim knot]

https://learn.adafruit.com/guides/latest

[desert orbit]

also glad to see an adafruit-maintained driver version! i wrote one and submitted it to the community bundle a long time ago now and haven't had time to keep it updated

[gray obsidian]

that'd make a lot of PWM channels for a 10x10 Flaschen-Taschen…

cf. https://github.com/hzeller/flaschen-taschen

(I wrote the vout support in VLC when I visited NoiseBridge 🙂 )

Hmm, how do they come on the reels? are they in packages or just stuck to a ribbon? Maybe they could be tested before rewinding the reel?

Oh, OK, peelable sealed package…

Patch your pick&place to have test filters maybe? 😅

For control of pant tilt I've also used a single thumbstick
https://www.adafruit.com/product/512

[unreal bay]

Was there any remote control 3-servo project from the past (ideally BLE, but wifi too - I seem to remember a quick show and tell maybe or a parsec)

[tulip canyon]

I found this handy if you want to specify different moves
https://easings.net/

RC Radio tranceivers make it really easy to control servos, I wonder if you could put Circuitpython in between?

[lavish patrol]

A well rounded Workshop today. 😉

oh yeah thanks @open surge I'll probably be off for the 4th!

[vestal terrace]

On new products ladyada refers to the new rp2040 as a "bones board". Whats meant by "bones"?

[sand lotus]

a bare bones board is a circuit design template that starts with the bare minimum for a feather, then you (or LadyAda) add other features to it. that way one doesn't have to start designing a new feather from scratch every time. it's a Feather PCB design starter template.

[vestal terrace]

Ah got it, thanks. Does that mean adafruit feather is technically a bones board…

[sand lotus]

no all feathers are different and have a lot of specific features. the bones board is an idea LadyAda came up with as a special PCB design for PCB designers to start with.

the feather is a form factor, not a single board... there are like hundreds of different feathers.

[gusty wedge]

Hi from Costa Rica

[unreal bay]

heya 👋 is there anything left on BLE land that you still wish for (but not now)?

[gusty wedge]

Well, I do have one. I have missed more than a couple of streams and cpy meetings.
What is the progress of bluetooth on the "new" esp's?

[unreal bay]

it works @gusty wedge !

Just got the accelerometer service working this week, which was the final bug I was aware of (from first testing)

It's merged, and tested 😄

[gusty wedge]

thanks a lot for the info @unreal bay, I will have to play a bit with a couple of projects I had in pause.

I think those huge imx have quite a massive DSP.

[glad mortar]

heyhey

oh yea tons

[timid plover]

do you need to write some python code to create a library for it?
does digikey or vendor have a footprint to download ?

[glad mortar]

what is the question?

will fit easily into JLC's constrains but you want to user their advanced service

I have done 0.35mm BGA pitch on JLC

so its about getting a footprint done atm?

you want via in pad yea

but its free on 6L

tho you don't need 6L for this likely

I'd just pay for via in pad and the 0.15mm drill, thats not a price point I would get hung up on

yea you pay mostly for setup costs there, mass production price is a different matter

does 0.8 pitch fit size wise though? It's a pretty huge package

there was a good talk on BGA fan out at Teardown, that might be helpful for you

not sure if its up yet

[timid plover]

are the teardown videos online yet - didn't find them yesterday ?

[glad mortar]

sure yea, it makes your live a lot easier

if you wanna penny pinch you can do it without but its so much more annoying

and risks yield issues

the slides of that talk are up at least
https://drive.google.com/file/d/1I1931z4apXfliXC8-JpewOcKAaWFj-AQ/view?pli=1

[timid plover]

stick with it - (the hardware )

[unreal bay]

BGA for the win, let's get schooled together\

[timid plover]

is the laptop linux also ?

[gusty wedge]

I do have a question. Not that I disagree, but why do you think these imx 10 chips would be nice cpy boards? (just +mhz/ram?)

And yeah, let's stick with hardware. This sounds like a cool deep dive indeed.

[glad mortar]

the main issue with high density stuff is generally that your vias pose a barrier for your traces, thats where HDI stackups with buried and blind vias come in but you can avoid them with good layout techniques that Greg describes in this talk/slides

[unreal bay]

whats you're most common module swap?

[glad mortar]

nice I got the 16" model recently

[unreal bay]

you saw the risc-v announcement for an upcoming framework mainboard

[gusty wedge]

Yeah, but even if I am quite the fan of riscv, these cpus are tiny in comparisson to let's say a pi4. I would wait.

[glad mortar]

btw can highly recommend to use SamacSys instead of making your own footprints

[unreal bay]

same @gusty wedge , feel similar with framework in general, the 16" looks great, but I would love a better mainboard + GPU option. Give it 18months

[glad mortar]

they are a Supplyframe company, its the service that gives you the footprints on the Mouser product pages. Very high quality usually and have stuff for nearly every part under the sun, there is a KiCad plugin too

https://componentsearchengine.com/search?term=MIMXRT1061DVL6B

the symbol you probably want to change, its more about getting correct footprints that are hooked up correctly

very easy to make mistakes with such high pin count parts

ah ok, yea thats good, same process then

just wouldn't do that by hand

if you are looking for recommendations for landing patterns you usually get that in seperate app notes for the particular package from the vendor

the SamacSys footprint is using 0.29mm pad diameter for this part

without promotion 6L was around 60-80$ starting cost usually but yea I think you can do that easily on 4, the main issues is through vias, not the amount of signals you need to run

for signal integrity 6L would be wiser but for a dev board of that purpose I don't think thats a big concern

I would always start with power layout

yea thats layout 🙂

putting the traces down is routing

[timid plover]

I followed and enjoyed @muted dragon and their layout work for the Glasgow interface explorer a few years ago - great experience

[glad mortar]

where do you have your PMIC atm?

I would probably put that more towards the corner where you got the flash atm given how much of the power input concentrate there

I mean yea what ever regulator, for these higher end SoCs you often need some power sequencing but haven't looked at the 1061 yet

ah okay, yea then I would take care of placing that DCDC circuit first, you want that to be tight

you can probably use a smaller inductor if the size gives you trouble

for sure, balls are often layed out so that you can just place the decoupling caps across them from the back

do double check if you can ommit connections, its not always the case that they are internally connected so might rely on a connection on the PCB side

[timid plover]

Here's his twitch stream for your convenience 🙂 https://www.twitch.tv/esden/videos

[glad mortar]

yea that more for 0201, smaller packages tend to be better for decoupling, they have a lower impedance.

yea they support that for Standard PCBA

but use whatever feels best, you can def. fit this with 0402

depends on who you ask 🙂

I currently design a board for a customer with 01005

limor would probably favor bigger caps 😄
The small ones are not great if you are the ones assembling the PCBs
Need fairly pricey machines and tight process control to make them work well

eh, I would ignore the courtyard

thats an insanely dimensioned courtyard for the footprint size

[timid plover]

what does the datasheet recommend - or are you getting design rule checker feedback ?

did the evk guide show layout as well as the schematic you are sharing?

can kicad import alegro ?

[gusty wedge]

192 pins on that footprint, it is insane.

It looked bigger in kicad :p

[glad mortar]

that looks like 0402 for the most part

the resistors might be 0201

without size reference I'd guess 0603 and 0402

[timid plover]

what signals/bus are length specific ( wavy lines )

[glad mortar]

they would note that in the bom but usually its just a rec. going smaller is always okay, larger I would avoid for decoupling, size has a bigger impact than the actual capacitance chosen for it

oh for sure, if you ever want this to be assembled at Adafruit you probably wanna avoid anything smaller than 0402 🙂

she did understandably lament about me using 0402 in the past for a contract design, you wanna be sure about your process choices. Esp. when you otherwise use larger parts in your setup

if you struggle to see it by the naked eye its 0201

hm that looks more like 0402

[timid plover]

did they provide the BOM for their EVK?

[glad mortar]

you can use the FFC connectors as reference, an 0201 perfectly fits between two 0.5mm FPC pads

I use them a lot for bodges on those

wait I do have a devkit for that chip too I think, I can check quickly against an 0201 part

ah nvm its TQFP package and for the smaller RT line
