PIXHAWK Autopilot

Flight Management Unit

This module is in active development, and will be available around late October from 3D Robotics (3DR [ https://store.3drobotics.com/products/3dr-pixhawk/ ]), (Unmanned Tech [ http://www.unmannedtechshop.co.uk/pixhawk-autopilot.html ])(BYOD [ http://www.buildyourowndrone.co.uk/3DR-Pixhawk-p/3dr-pixhawk.htm ]) and (UAV store [ http://www.uav-store.de/autopilot-1/pixhawk/#cc-m-product-8496353793 ]).

PIXHAWK is a high-performance autopilot-on-module suitable for fixed wing, multi rotors, helicopters, cars, boats and any other robotic platform that can move. It is targeted towards high-end research, amateur and industry needs and is the all-in-one combination of PX4FMU + PX4IO.

Key Features

high-power compatible)

dedicated processor and stand-alone power supply (fixed wing use)

override mixing modes (fixed wing use)





Power System and Protection




A number of peripherals have been designed for PX4 (all autopilots, including Pixhawk and FMU).

Digital Airspeed Sensor

This digital differential airspeed sensor has a very low offset, a high resolution and most importantly: Does not suffer from the noise induced by long cables and offsets in the ratiometric output on the old analog airspeed sensors. It features a Measurement Specialties (coincidentally swiss, too) 4525DO sensor, with 1 psi measurement range (roughly up to 100 m/s or 360 km/h or 223 mp/h). Its resolution of 0.84 Pa is quite good, and delivered as 14 bit data from a 24 bit delta-sigma ADC. It also measures temperature to allow to calculate true airspeed from indicated airspeed using the MS5611 static pressure sensor on Pixhawk. As the temperature is not influenced by the heat of nearby processing components, it is much closer to the air temperature than with the previous analog sensor setup. It comes with M3 / 6-32 mounting holes. It is supported on all PX4 autopilot generation boards

External USB Port

This port can be mounted on the outside of the plane / copter / rover and provides convenient access.

External Multicolor Led

This LED has the same functionality as the in-built led and can be mounted anywhere on the system.

I2C Splitter

This splitter allows to connect multiple peripherals to the I2C port, including the external compass on the GPS.

Supported Platforms / Airframes

Any multicopter / airplane / rover or boat that can be controlled with normal RC servos or Futaba S-Bus servos. More details are available on the airframe page.
