TinkerBoy Gameboy Zero PCB 1.1 Inconsistently Responding

[pbharrell]

Hi all, so I'm making my first game boy pi zero with the TinkerBoy 1.1 board (http://www.tinkerboy.xyz/product/game-b ... oy-zero-3/)

I got it all wired up according to these helpful guides:
http://www.tinkerboy.xyz/gpio-button-gu ... mment-2838
http://www.tinkerboy.xyz/wiring-guide-f ... ller-v1-1/

The issue I'm having is that sometimes the buttons will register perfectly fine and other times all of the will stop working altogether if I move it. I made sure to wire up everything correctly and the board is receiving 5v at all times. Any ideas on why I'm having this issue with consistency?

Hey TinkerBoy, thanks for the quick response! After a couple days away from the project I came back to it today to make sure of some things. First, I used my multimeter to make sure all my solder joints were good. Everything checked out. Not knowing what else to do I watched a video of somebody else using this board. He gave the tip to take a screw driver and go over the button contacts lightly to help them make better contact. Since I was out of ideas, I tried that.

I have no idea if that is what helped, but when I turned on the board that issue I was having completely went away, as strange as it seems. thanks for your suggestion about the bad rubber pads; it seemed like as good a guess as any.

Thanks for the update.

Yeah one of my previous builds with similar issues was solved by lightly screwing the board to make better contact with pads.
