Cerbuino Bee died?

Yesterday, I wanted to connect my board Cerbuino to control the load capacitor 400V with the assistance of a mosfet, unfortunately, I had to make a bad connection because now when I feed my board the processor immediately starts a heating and it is no longer recognized by the computer.
Do you think it is repairable ?
If yes, from where could it come ?

Don’t know about your location, but I destroyed a more expensive ChipworkX board to the point it draws high current and the CPU heats up, so sending for repair is about the same cost as a replacement board.

I think GHI offers a repair service so would be good to ask them first.
