Hey everyone

On my first bench test I made the wrong assumption that my receiver scales the input voltage. I have a 7.4V receiver pack hooked up to the receiver that’s hooked up to the AMP2. I then connected the AMP2 to the PC through USB. Initially everything seemed fine with light flashing. I continued to Mission Planner to set up the plane, although AMP2 fails to connect now.

It is still visible in the COM port and 3Dfix is solid so it does still get GPS lock. When I hit connect in Mission Planner the blue and red light (A, C) rapidly alternately flash for a couple of seconds and stop and the yellow TX and RX don’t flash. I can’t see any visible burn/scorch marks on the board.

Has anyone else supplied overvoltage to the board and is there a way to fix this?

Cheers!
