Help to recover burned DuetWifi, it is posible

It's great that the board works on USB power.
If it gets NO power when you supply external 5 Volts, I think your jumper might be bad.
Can you measuere the voltage on pins #1 and #2 on the bottom of the PCB jumper pins when you have ONLY the external 5 Volt supply connected?

@alankilian Good idea, I will to check the voltajes.
What should be expected with the pin EXT IN in place? without the pin in place what should be expected? -
Pin #2 will show 5 Volts with and without the jumper in place.
Pin #1 will only show 5 Volts if the jumper is in place and working. -
@alankilian thanks, I will check and return
