Holybro Pixhawk 6X-RT
WARNING
PX4 does not manufacture this (or any) autopilot. Contact the manufacturer for hardware support or compliance issues.
Pixhawk 6X-RT® is the latest update to the successful family of Pixhawk® flight controllers designed and made in collaboration with Holybro®, NXP's mobile robotics team and the PX4 team based on NXP's open source reference design.
It is based on the Pixhawk® Autopilot FMUv6X Standard, Autopilot Bus Standard, and Connector Standard.
Equipped with a high performance NXP i.mx RT1176 dual core Processor, modular design, triple redundancy, temperature-controlled IMU board, isolated sensor domains, delivering incredible performance, reliability, and flexibility.
TIP
This autopilot is supported by the PX4 maintenance and test teams.
소개
Inside the Pixhawk® 6X-RT, you can find an NXP i.mx RT1176, paired with sensor technology from Bosch®, InvenSense®, giving you flexibility and reliability for controlling any autonomous vehicle, suitable for both academic and commercial applications.
The Pixhawk® 6X-RT's i.mx RT1176 Crossover dual-core MCU contain an Arm® Cortex®-M7 core running up to 1GHz and Arm® Cortex®-M4 core running up to 400MHz, has 2MB SRAM and external XIP Flash with 64MB. The PX4 Autopilot takes advantage of the increased power and RAM. Thanks to the increased processing power, developers can be more productive and efficient with their development work, allowing for complex algorithms and models.
The FMUv6X open standard includes high-performance, low-noise IMUs on board, designed for better stabilization. Triple redundant IMU & double redundant barometer on separate buses. When PX4 detects a sensor failure, the system seamlessly switches to another to maintain flight control reliability.
An independent LDO powers every sensor set with independent power control. A vibration isolation System to filter out high-frequency vibration and reduce noise to ensure accurate readings, allowing vehicles to reach better overall flight performances.
External sensor bus (SPI5) has two chip select lines and data-ready signals for additional sensors and payload with SPI-interface, and with an integrated Microchip Ethernet PHY, high-speed communication with mission computers via ethernet is now possible.
The Pixhawk® 6X-RT is perfect for developers at corporate research labs, startups, academics (research, professors, students), and commercial application.
Key Design Points

E.g, to securely store operator ID or certificates.
- Modular flight controller: separated IMU, FMU, and Base system connected by a 100-pin & a 50-pin Pixhawk® Autopilot Bus connector.
- Redundancy: 3x IMU sensors & 2x Barometer sensors on separate buses
- Triple redundancy domains: Completely isolated sensor domains with separate buses and separate power control
- Newly designed vibration isolation system to filter out high frequency vibration and reduce noise to ensure accurate readings
- Ethernet interface for high-speed mission computer integration
- IMUs are temperature-controlled by onboard heating resistors, allowing optimum working temperature of IMUs
