Pixhawk Series

Pixhawk is an independent open-hardware project providing readily-available, low-cost, and high-end, autopilot hardware designs to the academic, hobby and industrial communities.

A number of companies have created products based on the Pixhawk designs, which all share the common architecture and have the same connections, outputs, functions, etc. The products differ in that they have form-factors that better meet certain use-cases.

Any flight controller that is based on a Pixhawk project hardware design is a "Pixhawk".

That said, the name "Pixhawk" is very overloaded. It is also commonly used to refer to 3DR's "Pixhawk" flight controller (based on the Pixhawk project's FMUv2 architecture).

The project delivers regular iterations of the flight controller architecture. The original specification was FMUv1. At time of writing controllers are being built using FMUv4, with new evolutions already being planned.

The following section lists the project architectures (in reverse order) and some of the associated products.




At time of writing this is the most popular Pixhawk architecture.

  • 3DR Pixhawk


  • Fixfalcon


  • HKPilot32


  • AUAV-X2


FMUv1 (first generation)

The first architecture had a two components: PX4FMU+PX4IO.

This is no longer available for purchase.
