6 Connect RC receiver
7 Connect motor outputs
Connect backup power (optional)
Pixhawk is compatible with PPM RC receivers or PWM receivers with an additional PPM encoder
module. Connect the three-wire cable (red, black, and white) from your PPM receiver or PPM
encoder to Pixhawk's RC pins with the white wire connected to the signal (s) pin, the black wire
connected to the ground (-) pin, and the red wire connected to the power (+) pin.
more information on using a PPM encoder or Spektrum Satellite receiver.
Connect the two-wire cable (red and black) protruding from the top plate to provide a backup
power source for Pixhawk. Connect the black wire to any of Pixhawk's main output ground
(-) pins and the red wire to any of the main output power pins (+). This configuration is best
supplemented with a zener diode
power method can be used without implementing the additional diode. If you do not wish to
connect backup power, leave the cable disconnected.
Locate the six-wire cable (multicolor) protruding from the
central space in the top plate. Connect it to the main output
signal (s) pins on Pixhawk according to motor number. Recall
your notes from the power system wiring and see which color
wire corresponds to motor 1. Ensure that that color wire is
connected to the main output 1 signal (s) pin. Do not rely on
the colors of the wires shown here, the accuracy of this
component is critical.
