Howdy, folks. Working on my first build (following the fantastic guides provided by wermy), but am having an issue with my controls. I've used a very basic button PCB from amazon, linked below, hooked up to a teensy. everything works great, except for the up button on the d-pad. I've checked all my wiring from the PCB to the teensy and it looks alright--good connections and such. Has anyone else encountered a similar issue? Beginning to wonder if I have a bad board... Thanks in advance!

Unlikely a bad board. Are you sure your code is ok? Re-solder the Up wire at both ends just to rule it out. I had a bad A button once but you wouldn't know by looking. Or use a multimeter
