Announcing the Pixhawk FMUv5X Open Standard

By September 13, 2021Announcements

The Latest member of the Pixhawk FMU Family

The new generation of Pixhawk FMU brings the proven features from previous generations to a hardened form factor. We are building on top of the battle-tested functionality of the FMUv5, with a modular design and triple redundancy.

Enabling extensibility and cross-vendor compatibility

The new modular design of the Pixhawk FMUv5X Open Standard features a System-on-Module (SOM) thanks to the Pixhawk Autopilot Bus (PAB). The SOM design allows for the development of baseboards that can extend the functionality of Pixhawk to include companion computers or customized form factors from vendors—guaranteeing cross-compatibility between manufacturers who follow the standards.

The FMUv5X delivers incredible performance and reliability, thanks to the STM32F7 and the unique sensor sets available for the standard, including sensors from Bosch®, and InvenSense®, giving you the flexibility to control any autonomous vehicle.

Proven Hardware Interface

  • Secure element for secure authentication of the drone
  • Ethernet interface for high-speed mission computer integration
  • Three redundancy domains: Completely isolated sensor domains with separate buses and separate power control.
  • It has redundant sensors on separate buses, allowing parallel and continuous operation even in the event of a hardware failure.
    • Some of the possible sensor configurations:
    • Bosch BMI088 accelerometer (vibration isolated)
    • Invensense ICM-20602
    • TDK Invensense ICM 42688-P
    • Bosch BMM150 compass (vibration isolated)
    • Two Bosch BMP388 pressure sensors
    • GPS external mag + baro #1 
    • GPS external mag + baro #2 
    • Calibration EEPROM for baseboard sensors 
    • On-IMU calibration EEPROM memory for high-accuracy sensors 
  • Automated sensor calibration eliminating varying signals and temperature
  • FRAM memory for configuration data
  • Operating temperature -40 to +85°C
  • Extensive power monitoring
    • Two smart batteries on SMBus or more on UAVCAN
    • 5V rail monitoring
    • 3.3V rail monitoring for CPU
    • 3.3V rail monitoring for each sensor domain
  • External sensor bus (SPI)
  • Redundant power supply: The autopilot can be powered from up to two power sources and every sensor set is powered by an independent LDO with independent power control
  • Battery-backed real time clock for running security applications without GPS coverage
  • NFC reader support

Fully compatible with PX4 Autopilot

The FMU5X Open Standard is fully compatible with the latest release of the PX4 Autopilot (v1.12), allowing for bigger workloads and task-intensive applications, providing a stable and safe baseline for manufacturers who wish to implement the standard—offering complete compatibility with our ecosystem of open source projects.

The first implementations are now available, more available soon

Made possible thanks to the Pixhawk SIG

The DS-011 standardization process took over twelve months of development, with contributions and participation from Dronecode Foundation members within the Pixhawk Special Interest Group during the FMU Workgroup meetings.

Dronecode Foundation members develop Pixhawk Open Standards to drive interoperability of the drone ecosystem through open-source. The DF facilitates an open process to develop open standards. The standards enable multiple implementations to be delivered into the market to benefit users and developers by enabling choices in a marketplace.

The standard is now available for everyone to download

About the Dronecode Foundation

The Dronecode Foundation (DF) hosts open-source and open-standard projects and their communities, forming an ecosystem of critical components to the Drone Industry. DF is a vendor-neutral foundation for open drone projects part of the Linux Foundation. We work with developers, end-users, and adopting vendors from around the world. DF provides a neutral space for collaboration in the development of open standards between engineers and organizations, members of the drone community, nurturing an open ecosystem providing open alternatives of hardware and software components key to the development of Uncrewed Vehicles.

About the Pixhawk

The Pixhawk project has provided readily available open standards for drone and open hardware for more than a decade. The Pixhawk SIG was formed to tackle the lack of specifications and guidelines for drone systems development and is supported by Dronecode Foundation members who support Open Standards.
