Supported Platforms / Airframes

Any multicopter / airplane / rover or boat that can be controlled with normal RC servos or Futaba S-Bus servos (S-Bus or servos: only in combination with PX4IO Airplane/Rover Servo and I/O Module, brushless motors controllers can be controlled with PX4FMU alone, up to four in a classic quadrotor setup.). More details are available on the airframe page.

Manual and Schematics

USB Driver

  • Windows: ZIP file, manual installation
  • Mac OS: Comes with in-built drivers, no additional driver for the micro USB port, but you need the VCP drivers (32/64 bit) on MacOS X Lion or above for the FTDI connection
  • Linux: Comes with in-built drivers, no additional driver needed

microSD Card Slot

Kingston microSD card with adapter

PX4FMU has a microSD socket and can read and write FAT (16 or 32)-formatted SD / SDHC cards (the default formatting of new SD / SDHC cards). It can log data on the SD / SDHC card or read configuration files.

Matching Peripherals

PX4FMU can be used on top of these carrier boards:

A list of all peripherals (RC receivers, GPS modules, telemetry / radio modems) is available on the PX4 Peripherals page.

Stacking Spacers

Spacers to stack PX4 boards, normally delivered with carrier boards (PX4IO Airplane/Rover Servo and I/O Module / PX4IOAR Quad Carrier) if bought from 3D Robotics.

  • Between-board spacers (8 mm (5/16”) height): Digi-Key Link for stacking e.g. PX4FMU and PX4IO
  • Below-board spacers (1.6 mm): Digi-Key Link For mounting PX4FMU on the airframe

Connectors

These jumper wires are suitable for the GPS (J4) and MULTI (J1) housings below.

PX4FMU 1.6 Pinout 

For the orientation of the connectors see the full manual.

Interface to other PX4 Modules

Standalone Operation

PX4FMU can be used standalone, without any stacked PX4 carrier board, for a wide range of applications. It has 4x servo out (PWM), I2C, 1 or 2 UARTs, battery voltage sensing and a low-current 3.3V power supply output on its multi connector (details) and requires 5V power input.

Supported platforms include:

  • Quadrotor/Multirotor frames (e.g. ArduCopter (PWM, 4 rotors), Mikrokopter (I2C, 4-8 rotors))
  • Small fixed wing aircraft (with a servo power harness and BEC)
  • Cars / Rovers / boats (with a servo power harness and BEC)

Stacked Operation

PX4 Stack viewed from left

The PX4 system has a stacking concept for combining the PX4FMU autopilot-on-module with a carrier board that interfaces to the airframe and provides a stable 5V power supply. This concept allows customized solutions for different vehicles whilst still sharing the same autopilot module. The image on the left shows PX4FMU Autopilot / Flight Management Unit and PX4IO Airplane/Rover Servo and I/O Module stacked as complete fixed-wing/car/boat solution.

Function Mappings

Many PX4FMU pins have multiple functions. These functions can be changed at runtime, with changes saved in the onboard EEPROM. The PX4FMU Multi Ports page explains this mechanism in detail.

Each column represents one function mapping: SRV is for PWM servo output, AR for the AR.Drone 1.0/2.0 motor interface. The 3.3V VDD pin is a 3.3V, 500 mA current-limited power output for peripherals, e.g. a radio modem. The 5.0V VDD pin is the 5.0V, reverse-polarity protected power input.
