MOUNT
Use the provided foam to mount Pixhawk as close as possible to your vehicle’s center of gravity.
Make sure to orient the board with the arrow pointing forward.
Vehicle front
Attach the foam squares to the
corners of the board.
GETTING STARTED
With the help of APM firmware, Pixhawk turns any
RC plane, copter, or rover into a full-featured personal
drone. Once you have a fully-assembled frame, follow
this guide to install Pixhawk.

CONNECT
(Required) Connect the buzzer
and safety switch.
(Optional) Connect a 3DR
Radio to Pixhawk’s Telem
port using the 6-wire cable
provided with your 3DR Radio
Kit to receive data and
communicate with
the autopilot in flight.
(GPS or GPS+Compass required)
Connect a 3DR GPS+Compass to
provide the autopilot with positioning
data during flight. This kit includes a
6-wire cable to connect the GPS ports.
Connect the MAG to the I2C port using
the 4-wire cable provided with the 3DR
GPS+Compass.
(Required) Connect the 3DR
Power Module to the Power port
using the 6-wire cable to direct
power from your lithium polymer
(LiPo) battery to the autopilot.
(Optional) The I2C splitter expands the I2C port to allow up
to four additional peripherals to connect to Pixhawk. Use the
4-wire cable to connect the I2C splitter and add a compass
module, external LED, digital airspeed sensor, or other
peripherals to your vehicle.
2
Connect the ground (-), power (+), and signal (S) wires to the RC
pins using the provided 3-wire servo cable.
For a Spektrum DSM, DSM2, or DSM-X Satellite RC receiver, connect to
the SPKT/DSM port.

FOR SPEKTRUM SATELLITE RECEIVERS
FOR PWM RECEIVERS
Purchase a PPM Encoder module to connect a PWM
RC receiver to Pixhawk at store.3dr.com.
LOAD SD CARD INTO PIXHAWK
If the SD card is not preloaded into Pixhawk, insert the micro-SD card into the slot at the
bottom end of the board.
For a complete list of RC systems compatible with Pixhawk, visit the APM wiki page here.
LOAD FIRMWARE
APM firmware is the brains of your autopilot operation and must be installed before using Pixhawk.
To load firmware onto Pixhawk, install a mission planner application on your ground station computer. Choose
either Mission Planner (Windows) or APM Planner for (Windows, OS X, and Linux).
Both applications are available for free download from ardupilot.com.
For rovers, connect the throttle and steering
wires to the main output signal pins.
Pin 3 = Throttle
Pin 4 = Steering

FOR COPTERS
FOR PLANES
FOR ROVERS
Connect each signal wire from the PDB to
the main output signal (S) pins by motor
number. Connect one wire for each motor
to the corresponding pin.
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
For planes, connect the control channel
wires to the main output signal pins.
Pin 1 = Aileron
Pin 2 = Elevator
Pin 3 = Throttle
Pin 4 = Rudder

INSTALL PLANNER
When prompted, follow the directions to load the firmware. Once the status bar shows that the download is
complete, power cycle the board by disconnecting and reconnecting the USB.
If you hear a musical tone, your firmware installation is complete. If you hear a series of tones followed by three
beeps, disconnect the USB and reconnect while holding down the safety button. Upon restart, listen for a series
of tones followed by two beeps indicating that your firmware has loaded successfully.

Select Accel Calibration, check the box for AC 3.0+, select Calibrate, and
follow the prompts to calibrate Pixhawk’s accelerometer. Make sure to wait a
couple of seconds before and after changing the positions of the vehicle.
Select Radio Calibration to teach Pixhawk to work with your RC
transmitter. Turn on your transmitter, select Calibrate Radio,and move
all sticks and switches to their extreme positions. Select Click when Done
once the red bars are set for all available channels.
Move each switch on your transmitter to its available positions. The mission
