Pixhawk Hardware

Pixhawk is the standard microcontroller platform for the PX4 flight stack. It runs the PX4 Middleware on the NuttX OS. As a CC-BY-SA 3.0 licensed Open Hardware design, all schematics and design files are available. The Pixfalcon is a smaller version of Pixhawk for FPV racers and similar platforms. For drones requiring high processing performance or a camera interface the Snapdragon Flight might be a more optimal fit.
