Pixhawk (power)

Hi, I connect -by mistake- 11.1 volt to the pixhawk board, now when i connect 5v the led of pwr the only one is turned on, by green color, did anyone know if there is any other way to power the board, or repair the damage that happened

thank you

Good day, you need check the voltage regulators and the components near it, check also the MCU and the FMU.
if only the voltage regulators are damaged you can try replace it, but better use that fc for an alternative useā€¦ like for rover or antenna tracker

where on the board did you apply the 11v?
