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.

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.
