RFD 900+ fried due to overvoltage (12V)

Hi all,

Hope y’all are doing fine. After years using this radio, I finally screwed up and fed it 12V instead of 5V.
I see signs of “electrical burn” right above the pin #4 and a fried microcontroler (left bottom one).
I can’t seem to find the schematics to identify what seems to be burnt and replace it, can someone point me to where I can see it?
Moreover, has this ever happened to any of you and, if so, how did you manage to fix it?

Any other tips are more than welcome!

Cheers

Hello did you figure out the problem?
