I just got a v3 and seem to have problems lighting a W2812 ring. The LED’s won’t light most of the time and when they do they don’t cycle as they should (they only stay lit solid in a seemingly random pattern and colors).
I’m using the USB to power the board, and WIFI works correctly. I’m not sure what the next steps are here for trouble shooting this issue.
Update: I can’t get any LED’s to light now
