The Pixfalcon autopilot (designed by Holybro®) is binary-compatible (FMUv2) derivative of the Pixhawk 1 design that has been optimized for space-constrained applications such as FPV racers. It has less IO to allow for the reduction in size.

- Pure Telemetry options:
Most users will not need to build this firmware! It is pre-built and automatically installed by QGroundControl when appropriate hardware is connected.
To build PX4 for this target:
Developers will need to solder wires to the board test pads for SWD, and to the STM32F4 (IC) TX and RX to get a console.
