I have been playing around with my 32x64 rgb Matrix by adafruit and also have a raspberry pi hat to go with it.
However I never got anything to work and I have the suspicion that I broke something since I realized that I plugged the data in the out instead of in one time. How can I test the individual parts if they are broken?
(Hat also had a spark one time, I think by shorting with my ARGON one rpi case)
And btw: I power the matrix directly (5v 3a)
