In case these issues are connected, is this the same problem with the YD-RP2040 mentioned in https://github.com/beekeeb/piantor/issues/22#issuecomment-2012335168 ?
My friend bought YD-RP2040 controllers and this same "hack" works on this. Shorting Vin and Vout on the master side lets the other side receive power.
This happens because the original Pico has Vbus and Vsys instead of Vout and Vin, respectively. Vsys can source current and the Piantor PCB has a trace running from Vsys to the TRRS port and uses that to power the non-master side. On the YD-RP2040 (and whatever the controllers here are) this pin is replaced with Vin, which cannot source current, and delivers no power to the TRRS port, although it can receive power from it.
Hello, I had some major struggles with getting a YD-RP2040 to work on the PCB and have a PR ready to go that add notes to the
README.md
explaining how to make the YD-RP2040 work on the Piantor.If you don't want to give me access to open a PR, I can paste the notes I have here for you (in the BOM table)
Thanks!
