Flight Controller Selection

You should select a board that suits the physical constraints of your vehicle, the activities you wish to perform, and of course cost.

PX4 can run on many flight controller boards and systems (see Autopilot Hardware, or the list of supported boards here on Github). A subset of the available options are listed below.

Pixhawk Series

Pixhawk Series open-hardware flight controllers run PX4 on NuttX OS. With many form factors, there are versions targeted towards many use cases and market segments.

If you need computer vision or other computationally intensive tasks then instead consider a board with companion computing.

Controller Description
mRo Pixhawk Popular general purpose flight controller (this is a slightly updated version of the discontinued 3DR Pixhawk 1).
Also consider: MindPX, HKPilot32, Dropix.
Pixracer Very small/light autopilot optimised for FPV racers. It is suited to any small frame that requires no more than 6 PWM outputs.
Also consider: Pixhawk 3 Pro, MindRacer, Pixfalcon.
Pixhawk Mini Small general purpose autopilot that has been optimised for ease of setup.
The controller has internal vibration damping and only 8 main outputs (no AUX ports), making it much less daunting to install and connect. It is not suitable for vehicles/functions that require AUX ports.
Pixhawk 2 Flexible autopilot intended primarily for manufacturers of commercial systems. It is designed to be used with a domain-specific carrier board in order to reduce the wiring, improve reliability, and ease of assembly.

Autopilots for computationally intensive tasks

These flight controllers offer on-vehicle "companion computing", enabling computer vision and other computationally intensive tasks.

Controller Description
Qualcomm Snapdragon Flight A high-end autopilot computer that runs PX4 on the DSP (on QuRT RTOS). It includes a camera and WiFi.
Intel® Aero Ready to Fly Drone A UAS development platform that integrates a powerful Linux computer, PX4 on NuttX, and a camera in a single package.
Raspberry Pi 2/3 Navio2 RaPi can be connected to an autopilot and used as a companion computer.

Commercial UAVs that can run PX4

PX4 has been ported to a number of popular commercial drone products, as listed below. This allows you to add mission planning and other PX Flight modes to your vehicle.

Controller Description
Crazyflie 2.0 A micro quad (27g) created by Bitcraze AB.
Parrot Bebop A popular lightweight flying camera.
