[SOLVED] tinkerBOY v1.1 Issue - Lagging/Freezing with Button Presses

[kryan]

Good day All,

I'm having an issue with a recently completed build using the tinkerBOY v1.1 board. Pressing or holding down certain buttons causes the system to lag then freeze entirely. Single presses on these buttons also have a hard time registering. This is using tinkerBOY's custom RetroPie image with GPIO controller already pre-installed

Initially, none of the buttons registered making controller setup impossible. Following the advice in this user's thread https://sudomod.com/forum/viewtopic.php?f=44&t=6206 I cleaned the pcb contacts and replaced the silicone pads. This change allowed button presses to register and initial setup to be completed, however the lagging/freezing issue now persists.

Hey. Thanks for the reply. That was the thread I was referring to. Cleaning the pcb did help a bit initially, but didn't solve the issue completely. Will go over the board again and double check my wiring.

You might want to try another silicons.

You can test the pads with a multimeter in continuity mode...
oh, and confirm if the pads are really for GB, not GBC (i think they are shorter)

Hey everyone. Thanks for the feedback. Going over the board with an eraser this time plus some more isopropyl alcohol did the trick. Buttons are super responsive now. No more lag when holding buttons down either.

Good to ear that!
Your build looks good
