PX4 does not manufacture this (or any) autopilot. Contact the [manufacturer](https://www.nxp.com/) 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 (opens new window).
The NXP FMU and included peripherals have been tested to comply with FCC/CE/RoHs/REACH directives.
These flight controllers are manufacturer supported.

This FMU is provided only as a kit, and includes Segger Jlink EDU mini debugger (opens new window), DCD-LZ debugger adapter, USB-TTL-3V3 console cable, HolyBro GPS module, battery power module, SDCard and case, screws and stickers. Telemetry radios (HGD-TELEM433 (opens new window) and HGD-TELEM915 (opens new window)) must be purchased separately to match ISM band frequencies used in your country.
A "Lite" version RDDRONE-FMUK66L is also available which does not include the power module, GPS, Jlink or USB-TTL-3V3 console cable or SDCard.Scroll down to see FMUK66L in the buy section of the FMUK66 buy page (opens new window)

# 组装 / 设置
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:
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 (opens new window).
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.
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.
The NXP HoverGames Drone Kit (opens new window) (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.
