Pixhawk® is an independent project aiming at providing high-end industry standard autopilot hardware to the academic, hobby and industrial communities at low costs and high availability. It provides hardware for the Linux Foundation DroneCode® and PX4® projects. It originated from the PIXHAWK student project. The rightful owner of the Pixhawk registered trademark is Lorenz Meier.

We are always looking for new developers! Get in touch via our Discuss Server (discuss.px4.io).

Autopilot Software

The Pixhawk autopilot module runs a very efficient real-time operating system (RTOS), which provides a POSIX-style environment (i.e. printf(), pthreads, /dev/ttyS1, open(), write(), poll(), ioctl(), etc). The software can be updated with an USB bootloader. We support multiple flight stacks: PX4 and APM®.

Autopilot Hardware

Pixhawk 4 (coming soon!) is the latest update to the successful family of Pixhawk flight controllers. It is designed and developed in collaboration with Holybro® and the PX4 team. Optimized to run the full Dronecode stack, Pixhawk 4 comes preinstalled with the latest PX4 firmware (v1.7).


  • 2 Bit Arm® Cortex®-M7 with 216MHz, 2MB memory, and 512KB RAM
  • Will start shipping from early May 2018. Order from: Holybro®

The Pixhawk project has a lot more hardware units to offer, including an optical flow sensor board. Check out all Pixhawk hardware modules.
