Ok I have had my pixhawk powered up on usb a few times no issues while I was waiting for parts to arrive. Got everything I needed and started the build. Motors got calibrated and soldered on the distribution board. Power module connected via xt60 to the distribution board and I powered up the pixhawk. No problem
Then I connected the motors to the pixhawk. Hobbypower simonk 30a. With the bec power wire still plugged in. I was already to calibrate. I plugged in the battery and a few seconds later magic smoke from the pixhawk
Before I hooked up the esc’s to the pix I read and saw on the sight that they connected all three wires.
But by not disconnecting the bed wires did it fry the pixhawk?
I need to know why before I by another. Don’t want to smoke another
