Connect an RC Receiver

If you ordered an RC transmitter with your RTF aircraft, this process has already been completed for you.

Pixhawk is compatible with PPM RC receivers, Futaba S.Bus receivers, and Spektrum DSM,DSM2, and DSM-X Satellite receivers. For traditional single-wire-per-channel (PWM) receivers, a PPM encoder can be used to convert the receiver outputs to PPM. For a list of RC systems compatible with Pixhawk, click here.

1 Connect

For PPM receivers and Futaba S.Bus, connect to the Pixhawk RC pins.

black wire = ground
red wire = power
white wire = signal

For Spektrum Satellite receivers, connect to the SPKT/DSM port.
