I am using the Pixhawk 4 and PM07 power module for my Rover. I have connection as
Pixhawk PM07
FMU PWM OUT --------> FMU PWM IN
I/O PWM OUT ----------> I/O PWM IN
I have connected Servo signal Pins to FMU PWM OUT 1 and ESC signal to FMU PWM OUT 2 on PM07.
But when I try to use my Radio which is connected via receiver TGY-IA6B on pixhawk PPM RC port it do not work. . . .After reviewing online resources i changed the connection I/O PWM OUT from pixhawk to FMU PWM IN on PM07.
Now, Only Servo is working with my radio. I have tried all the FMU PWM OUT pins on PM07. But only the Pin 1 works whether i connect servo or ESC to it.
Thanks
