Need help reading Gameboy pocket button portion of pcb
Need help reading Gameboy pocket button portion of pcb
Hey I'm new to electronics, but I'm building a Gameboy pocket pi right now and need some help. I'll be using the lower portion of a pocket PCB for my controller but am having trouble figuring out how to read the layout. I'll be using a teensy for the controller. I need to know which lines to solder wires to for the buttons and which ones are the grounds. I've been following this guide http://www.xodustech.com/projects/raspb ... boy-pocket but was just hoping someone could explain to me what's get soldered where and why. Thanks in advance!

Re: Need help reading Gameboy pocket button portion of pcb
My suggestion is to not bother with the original PCB.
But if you want to wire it you'll just need a multimeter and find some vias or test pads which connect to the button contacts points.
Hard to say what's what, as it's hard to see the traces in the picture.
Alternatively you could just go here and grab the Gerber files and go somewhere like jlcpcb or oshpark and get the custom boards made up. Much easier. (I've just linked the button /audio board, but there are other variants too)

Also note you can skip the teensy if you like and wire buttons directly to the pis gpio pins and use adafruits retrogame utility. (That was you don't need to use up a usb port for the teensy.) But using a teensy is fine too.

Re: Need help reading Gameboy pocket button portion of pcb
Thanks for your response Rodocop! I just scratched off some of the PCB to reveal the copper and used the multimeter. I can see now how the traces are laid out, thanks for the advice. I think my next project I'll go with a premade board. And I'm also going to look into returning my teensy and wiring directly to the pi, one less piece of hardware. Thanks again!
