I litterally cannot find it anywhere on how to wire this
The only thing any of the pigrrl schematics show is connecting wires from b1,2,3,4 to pins on another board. Last time I checked adafruit, you need a positive and negative pin. This isn't redstone, you can't just connect one wire and hope it works. On top of this bad documentation the stuff isn't even labeled right. All that's labeled is G,G,b1,b2,b3,b4. Wtf is G and why do I have two of them?!?! Where do I connect power and where do I connect ground!?!? Plz help.
