You haven’t bothered providing us with the version of Pixhawk you’ve got there.

Besides, the servo rail shows what appears water marks. If that’s the case I wouldn’t use the board anymore for any flight activities.

I haven´t bothered because i´m not sure what model is, the housing says Pixhawk Pro, but inside the PCB looks like my other Pixhawk 2.4.8. And no these are not water marks. Anyway i could get a similar diode from another board.
