Everything checks out except pin 62, which just gave me zero volts.
I have had the board about 3 days, but I have a deadline by the end of the month
for this robot to work (im writing an article for servo)- so if the fix is just a few minutes with soldering iron, I would like to
go for that.
If you have time, Could you please explain to me how to fix this?
Otherwise, I will just email Don.
