What happens to a Pixhawk if I accidentally put a +12V onto the servo rail?

Posted by Nicholas Witham on October 31, 2015 at 10:43pm

I did it by accident for about 30 seconds, before I realised what the cable was. I originally thought it was the power cable to my Hawkeye receiver.

I didn't have any other power going into it at the time.

The pixhawk is a 3DR one.

I haven't tried to power it up yet since then, just waiting for some guidance from the pros first.

      You could have searched the Ardupilot wiki under Powering the Pixhawk and gotten your answer at http://copter.ardupilot.com/wiki/common-powering-the-pixhawk/#advan...

      Under these conditions the system will not draw any power (will not be operational), but will remain intact.
      Power module input (0V to 20V) [refers to the voltage coming into Pixhawk from the power module]
      Servo rail input (0V to 20V)
      USB power input (0V to 6V)
