[QUESTION] GPIO25 pin mapping #2

Open bmweller opened 2 years ago

bmweller commented 2 years ago

Is GPIO25 on the RP2040 wired to anything on the board?

sbcshop1 commented 2 years ago

@bmweller No, GPIO25 is not wired to anything on the board.

@sbcshop1 thank you for confirming, it might be ideal to port this pin out to a pad for soldering in a future revision? For example, I'd like to experiment on this board using other WIFI firmwares. Having a spare pin 25 pad means I can readily solder a fixed line to the 8266 GPIO0 and programmatically enter its bootloader mode by running the RP2040 as a passthrough programmer to flash the ESP.
