PicoCart64-lite v1: Add solder bridge jumper to support WeAct RP2040 pinout #42

Closed kbeckmann closed 2 years ago

kbeckmann commented 2 years ago

The official Raspberry Pi Pico pinout has 3V3 on pin 36. 3V3_EN is on pin 37, and is connected to VSYS (5V/VUSB) through a 100K resistor.

On the WeAct RP2040 boards, Pin 36 is GPIO29, and 37 is 3V3. This means that the pins 36 and 37 need to be connected together. However, this must not be done on the official Pico boards.

Add a solder bridge jumper to do this easily, but add a clear warning/explanation so people don't bridge this by mistake.
