Interesting … received my replacement chips and added them to the board one by one as I tested. No difference – however, I pushed down on the LED driver #2 (inner one of the two on the left side of board) and the blue LEDs on the right side of the board barely lit (but they lit). Maybe I need to resolder the socket?
I have not uploaded any sketches because, well … I can’t figure out how. My Arduino IDE does not seem to recognize the Peggy 2 board.
