Pixhawk 6c + PM07 + ESC4in1

Hello everyone, this is my first time working with Pixhawk. I connected it according to the scheme, but I ran into a problem, the servos do not work, I measured the voltage of 5v supplied. Also, the motors do not give a ready-to-start signal. Can you please see the schematics, is everything connected correctly? What did I forget?
