Your go to dev board for Gameboy accessories development. Put it on top of Wemos D1 mini and have fun.
This board uses the following pins:
D1, D2, D3 (Pull GPIO0 to ground), D5, D6, D7
Hence it is NOT compatible with Wemos SD card shield (check the microsd branch for microSD shield compatibility)
The part list is included as a Digikey shopping cart. Quantities are for one (1) board.
Note that EXT PORT AGB connector is not included. It must be sourced elsewhere.
