Just a simple cheap board that allows you to hook up some wires to all of the 32 pins so you can:
Debug a Gameboy reader/writer
Solder on a cartridge slot to the end, cut a cartridge so it fits and debug a game whilst it's being played on a Gameboy or inspect how a Gameboy reader/writer accesses it
Confirm all contacts work when repairing the cartridge slot
Updated v1.1 PCB has the 32 pin pads on the back too.
The PCB finish is now ENIG (as of 25 Jan 2021). You will receive the bare PCB only.
