Pixfalcon Flight Controller (Discontinued)
:::warning This flight controller has been discontinued and is no longer commercially available. :::
:::warning PX4 does not manufacture this (or any) autopilot. Contact the manufacturer for hardware support or compliance issues. :::
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.

Building Firmware
:::tip 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:
make px4_fmu-v2_default
Debug Port
This board does not have a debug port (i.e it does not have a port for accessing the System Console or the SWD interface (JTAG).
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.
