LED bug on the Waveshare (copy) RP2040-Tiny v1.1
Yoti opened this issue · comments
Hello!
I have a Waveshare (AliEx copy w/o Ws logo) RP2040-Tiny. It has "Rev1.1" mark on the bottom side. There is a problem with LED indication on it.
- FW 2.67 can output light, but it will ends with infinite green even without connecting the board (only USB to PC)
- FW 2.70+ has no LED output at all, but according to Reddit it can be fixed via removing some resistor near the LED
There are some docs for you:
- RP2040-Tiny Schematic
- V1.1 Schematic
- RP2040-Tiny Adapter V1.1 Schematic
- Working RGB LED sample (tested on my v1.1)
Feel free to send some test builds!
Regards,
Yoti.
Please check, if the D_IN pin of the LED has a resistor connected before going to the RP2040 chip. You might have to remove (break off) this resistor.

@Quas7 @martimparente the LED is working OK, but not on the Picofly. I don't want to break anything, I made a bug report for the developer.

Software can not fix hardware issues...
