Hi everyone, has anyone used the RP2040-Zero?https://www.waveshare.com/wiki/RP2040-Zero
My Nano with the CH340 has been intermitting at times. Looking to move to the RP2040.
I want to try build the GDU1400 (G3000) and this board seems to have everything I need. Enough GPIO pins to control the buttons and the backlight. A 5V to power the LEDs.
Any thoughts on this board? Is it fully compatible with Mobiflight.

It probably will work, but why that board instead of a regular Raspberry Pi Pico?

Yes, I tested this Zero and the function with MF OK - be careful when defining the mfmc file

The number of pins is not the same obviously - but I guess someone with one could define a board.json for it to set the correct pin layout?

I just don't need all the pins. This seems like a good size to plug into a custom PCB with female headers.

aren't they more expensive than a regular Pico?
if you are making a custom PCB, depending on how experienced you are at it, you could also just include the pico parts directly on your PCB. That's even cheaper.

They are just under £2 on Ali Express.

A normal Pico is $0.99

I have been looking at that actually. Started drawing up some schematics but it seems like its probably easier and cheaper to buy a RP2040 Zero and add it on.

I see some for as low as $0.49, although I'm not sure how reliably they'd be

I should take a good look on Aliexpress and see if I could get my hands on one.

I have a base design for an RP2040 that's been used several times to make custom PCBs here, see https://github.com/neilenns/KiCad7-Components/tree/main/RP2040 Base Design
Putting a pico on via headers is definitely less design work

Just checked Ali Express, the pico is roughly the same price.

What service would you use for PCBA service? I've been looking at JLCPCB.

yes, that's what pretty much everyone here uses. See the #pcb-design-archive channel for more
they are cheap, you can get coupons from them via their facebook page
note that we've had recent discussions about occasional RP2040 boards not working https://discord.com/channels/608690978081210392/1219965481214279690

this must be some US market targeting
for me its like 3€
or more even
and of course now that its the annual sale at ali, its like "now 2.64€, was 8.75"
as if it ever was 8€
but got to have that -70% sale with the same price as before
simple cipher
If you search for "RP2040" I'm finding cheaper boards than if I search for "Raspberry Pi Pico"
sure is temptin gto order some even though I don't need them
limit 1 😦

The price of 2040 is probably a lot less than the price of our work on flying toys 🙂
