PPM-SUM and S.BUS receivers connect to the RC ground, power and signal pins as shown. Spektrum and DSM receivers connect to the SPKT/DSM input. The instructions below show how to connect the different types of receivers to Pixhawk:

You will need to select a compatible transmitter/receiver and then bind them so that they communicate (read the instructions that come with your specific transmitter/receiver). # Radio ControlĪ remote control (RC) radio system is required if you want to manually control your vehicle (PX4 does not require a radio system for autonomous flight modes).

If not, you will need to setup a 5V BEC to connect to one of the free Pixhawk ports (without power, the servos will not work). Often the main pusher/puller motor uses an ESC with an integrated BEC (opens new window) that can be connected to the Pixhawk output rail. For copter this does not matter because the motors are separately powered.įor planes and VTOL the output rail will need to be separately powered in order to drive servos for rudders, elevons etc. The power module supplies the flight controller itself, but cannot power servos and other hardware connected to the controller's output ports (rail).
