@zibby said in I think I have ruined my Duet 2:
I measure 1.08 V on #2 and -3.2V (negative) on #3.
That can't be right.
Can you try again?
Although if the processor is getting hot, I guess it's got a problem.
I just wouldn't want you to go through all the trouble of replacing it when you've got impossible voltages right now. It would just blow up again.
