Pixfalcon Flight Controller (Discontinued)

注意

This flight controller has been discontinued and is no longer commercially available.

PX4 does not manufacture this (or any) autopilot. Contact the [manufacturer](https://shop.holybro.com/) for hardware support or compliance issues.

The Pixfalcon autopilot (designed by Holybro^® (opens new window)) 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.

提示

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调试端口

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.

Serial Port Mapping

UART	设备	Port
UART1	/dev/ttyS0	IO Debug
USART2	/dev/ttyS1	TELEM1 (No flow control)
