Changes from v1.0 to v1.1:
- Updated screw terminal labels to a more arcade-friendly scheme (same order, different names).
- Updated RGB LED connector to a JST-PH 4-pin connector, compatible with Paradise Arcade’s Kaiamana LEDs. Just plug them in with their wire harness then configure, no need for their driver PCB!
- Added 2 expansion ports (1 STEMMA QT/QWIIC compatible) for I2C peripheral support, such as OLED displays and future supported modules.
- Added connector for up to 3 programmable buttons or analog inputs (only 1 if I2C is used).
- Added 2-pin header for the RUN pin, which acts as a reset switch and can help get into firmware flash mode without opening the enclosure.
- Updated screw terminal and 20-pin to use 5v from VBUS instead of 3.3v.
- Added protection circuit to RGB LEDs.
- Added debug connector (for the 2 people other than me that may use it).
Every single GPIO pin of the Raspberry Pi Pico is now routed somewhere on the board…and some to more than one place! Some features such as programmable buttons and analog support will require a firmware update when GP2040 supports them in the near future.
