I've been confronted with a big problem.
I am using APM2.5 + the Power sensor board to provide the +5V.
The output JP is removed to provide seperately power to output (gimbal servos).
I experimented with a new PPM converter which didn't work yesterday. The guy who build it said I shoud check power. I did and found 4,4V on the input line.
Then I saw smoke and now lights are out for the APM2.5.
The power-meassurment-module provides 5,3V!
The APM2.5 is still alive, but only when powered directly by ESC on the Input line.
So is there any fuse on the power supply/meassurement port?
I don't know what to do. I am devestated. I need some ideas. Please.
