Fried DUE with 12v into 5v pin. Can I repair it?

Official Hardware Mega Due

Hi,

I accidentally fried an Arduino DUE by providing 12v in the 5v pin.
When I did it, all the onboard leds turned on! I disconnected it in less than 3 secs.

Now, after unwiring the board, when I connect it through the USB port:

  • The previously loaded program does not run anymore.
  • The L and ON onboard leds stay on.
  • The Arduino IDE does not recognise the presence of the Arduino. Neither through the programming port, nor through the native port.

Is there any chance to repair it?
Usual burnt suspect?
Links to troubleshooting guides to understand which is the burnt component?
Just hang it to the wall in front of my desk? (Remember: do no do it again!)

Thanks,
F

After 3 microseconds it was completely toast... You can't get away with such gross overload.

If you have a hot-air rework station you could replace the ICs and regulators and
probably get it working again, but its fiddly work and there might be other damaged
components.

Always check circuits twice, always check before applying power.
