Yet Another Pocket Color (YAP)

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.

ORDER AT 1MM WITH ENIG

You can support me on Ko-Fi or by buying the board directly from me my store

I also occasionally sell pre built PCBs on my store.

Building

[!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.

My recommendations

• New power regulator like my Safer Charge DC
• Q5 OSD Game Boy Color screen. The OSD allows you to move the screen
• Funny Playing Game Boy Pocket shell, with this shell you wont need to perform any trims.

New parts

• Thumbwheel

Update log:

Feb25: added pinouts for battery and 5V for testing and also my Safer Charger battery indicator LED board. Fixed some shielding pins, tied them to ground.

Jan26: changed the CPU footprint to be a bit more forgiving

Thanks

• Hozy for the original Pocket Color concept
• Console and Casks for the thumbwheel circuit
