Hi, I am using an an arduino board V3 in a system and I killed some of them .
-One was because one wire connected to 5V touched GND or some other, while arduino was connected to USB.
-Another was testing a board that had an shortcut from 5V to GND, and also was supplying 6V to some analog inputs.
Both arduinos doesnt respond anymore, either external supply neither USB supply. I think this arduino board have protections and so, and seem difficult to me to kill so easily an arduino, just with 5V supply. So, there is some recovery that I could try to recover them? Or some part of the board I should check/repair)
Thanks in advance
