Poco = Pocket Color. This project allows you to put a Game Boy Color in a Game Boy pocket shell. Full pocket colour PCB using the original parts. This board is made with modern screen kits in mind meaning it does not have the voltage rails for the original screen.

[!WARNING] I am not responsible for your skill issues!

This board uses all the parts of an original Game Boy Color minus the IR and original screen circuit. Most parts are in the same spot, however if you are having trouble you can check the interactive BOM

The thumbwheel circuit can be connected to an OSD screen to control brightness. The two touch pad wires and be conneced to the pads labelled ↑↓ on the back top left side of the board. The select, A and B pads are easy connection pads for the screen also.
