NXP RDDRONE-FMUK66 FMU

:::warning PX4 does not manufacture this (or any) autopilot. Contact the manufacturer for hardware support or compliance issues. :::

RDDRONE-FMUK66 FMU is a reference design using NXP Semiconductor components that closely follows Pixhawk FMUv4 specifications while adding two wire automotive Ethernet 100BASET1 and secure element A71CH (RevC) or SE050 (RevD). NXP provides the schematics, gerbers, BOM and source files so that anyone can duplicate, change or repurpose this design.

This is the official FMU for use with HoverGames.

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 nxp_fmuk66-v3_default

Debug Port

The PX4 System Console and the SWD interface run on the DCD-LZ FMU Debug port.

NXP's DCD-LZ is a 7 pin JST-GH connector and adds the nRST/MCU_RESET pin to the Pixhawk 6-Pin standard debug port.

The DCD-LZ breakout adapter permits the use of a standard 10 pin JTAG/SWD interface (i.e. using the Segger Jlink) and a standard 5 pin FTDI USB-TTL-3V3 type cable.

Supported Platforms / Airframes

Any multicopter / airplane / rover or boat that can be controlled with normal RC servos or Futaba S-Bus servos. The complete set of supported configurations can be seen in the Airframes Reference.

HoverGames Drone Kit

:::tip The NXP HoverGames Drone Kit (shown above) is a complete drone development kit that includes everything needed to build a quadcopter. You only need to supply the 3S/4S LiPo battery. :::
