Hi, I´m on my way to build my first Gameboy Zero Mod. I decided to use a Raspberry pi 3 B for this. My goal is that i want to leave the Raspberry pi as complete as possible means I don´t desolder any ports. Also I want to have accsess to the HDMI port so I can use it as a Retrostation. I also want that I can easily remove the Pi so I don´t want to use a lot of hotglue and no hotglue to fix the Raspberry at all.
Since I´m quite practiced in PCB designe I created my own custom Button PCB with integreated Battery charger, boost Circuit, overdischarge, overcurrent and overcharge Protection. The PCB has also place for a PAM audimodule, an aux port, volume wheel pins, pins for a speaker (also stereo Speaker) and an USB-C connector to charge the battery.
The PCBs are ordered and until now I wait for them.
To get the design-files look here
Until now I have modded the case to fit the raspberry pi, added the screen and set the pi up. Down bellow some first Images.
Inside It looks like:
The closing is until now not that straight forward but I have ideas for that
What I plan to do is to add an acrylic screenglass and of course ad an X/Y/R1/R2 Button and a speaker. I also will use the original Battery compartment with 4 15400 1200mAh lipos in parallel so I can charge them with my PCB. Also I want to add a part of a gamecartridge to hide the part of the display controllboard and the button board of the Display.
I´m also working on a V2 of the PCB with a safe turn off circuit maby you have some ideas I can add to the PCB?
I will update you when I´m recive the PCBs and test them. And if you have any suggestions/ tips and tricks for my build I would be very glad if you share them with me.
