Pixhawk Wiring Quick Start

This article provides high level information about how to power Pixhawk and connect its most important peripherals.

Do not connect any servos or other devices to the PWM outputs of your receiver. The RCIN port on the Pixhawk is designed for low power devices only, and a servo or relay may draw a lot of current from the receiver. If you connect a servo directly onto your receiver while the receiver is powered from the RCIN port of your Pixhawk you may damage your Pixhawk.

Power Pixhawk

Pixhawk is typically powered via its “power” port, as shown in the picture below. The power port simultaneously powers Pixhawk and reads voltage and current analog measurements produced by an optional power module. Information about powering the Pixhawk can be found in the topicPowering the Pixhawk.

Connect remote control inputs

Pixhawk is compatible with

  1. PPM remote control (R/C) receivers
  2. Futaba S.Bus receivers
  3. Spektrum DSM and DSM2 receivers
  4. Spektrum DSM-X Satellite receivers
  5. MULTIPLEX SRXL version 1 and version 2 receivers.

For traditional single-wire-per-channel (PWM) receivers a PPM encoder can be used to convert the receiver outputs to PPM-SUM.


Information about compatible receivers and how they are connected can be found in Compatible RC Transmitter and Receiver Systems (Pixhawk).

Connect buzzer and safety switch

The buzzer and safety switch button are mandatory for Pixhawk. Connect to the BUZZER and SWITCH ports as shown.


Mount the beeper at least 5cm away from the flight controller or the noise may upset the accelerometers.

3DR GPS+Compass

The3DR UBlox GPS + Compass Moduleis the recommended GPS for Pixhawk on ArduPilot. The GPS ports are connected with the six-position DF13 cable, and the MAG port is connected to the I2C port with the four-position DF13 cable.

The topic3DR UBlox GPS + Compass Moduleshows how to connect to Pixhawk and include additional configuration and mounting information.

Connect Motors

For Copter seeConnect ESCs and Motors.

In overview, for copters connect each signal wire from the PDB to the main output signal (S) pins by motor number:

  • Pin 1 = Motor 1 - - Pin 5 = Motor 5
  • Pin 2 = Motor 2 - - Pin 6 = Motor 6
  • Pin 3 = Motor 3 - - Pin 7 = Motor 7
  • Pin 4 = Motor 4 - - Pin 8 = Motor 8

Connect other peripherals

Depending on your hardware there may be any number of other peripherals attached, including sensors, cameras, grippers etc. These can be found as sub-pages of the topic Optional Hardware.

Information about connecting these peripherals to Pixhawk is found in the respective pages.
