Shorted board, blown TR5



  • Well, I did a very stupid thing and mixed up my main VIN connections on my Duet 2 Wifi 1.04 . As soon as I powered the board on, there was a puff of smoke and a small flame from the mosfet at TR5. The board does not seem to connect to Wifi or the Paneldue any more.

    I've found the part number for the burned mosfet (PMV40UN2) but that seems to just be a fan control component. Two of the fuses also blew, F2 and F3. Will I be safe to try powering the board up after replacing the fuses and correctly connecting the power input? Is there anything besides the mosfet to look out for?

    Thanks for any input, feel like a bonehead for hooking it up backwards.
