New into Raspberry Pi

Hi,

I am new in the forum, and I'm also quite new in the Raspberry Pi world (not electronics) and I am willing to build a MintyPi, but I have a big question.

I'd like to know what the "button PCB" does. I'm not asking for an schematic (I've seen people ask for that, but that's not my purpose), I would like to know what do the pins on the Raspberry Pi do when soldered to the PCB (sorry, it is being hard for me to explain myself in english). I would understand if you don't want to answer this question for confidential reasons.

I am waiting for the Button PCB and screen kit to be out so that I can build it.

Thanks for your help.

i'm not sure on all the exact details behind it. But using adafruits retrogame utility it will read the GPIO pins as keyboard strokes, which are then registered as game buttons in retro arch.

Each button pad will be wired to a specific GPIO pin, and all of them will use a common ground. When the button is pressed the GPIO is grounded and then it is registered as a press.

That was exactly what I was looking for.

Thank you very much, I really appreciate it :)
