PX4 Hardware

The PX4 project designed a series of hardware modules used to guide vehicles in both human-assisted and fully-autonomous operation. The currently available modules include the main autopilot (called FMU – Flight Management Unit), platform-specific carrier (called IO – input/output) modules that output servo signals and motor commands and an optical flow camera module.

All modules are CC-by-SA open hardware designs. Notes on commercial hardware offerings and open hardware

Autopilot Modules
