The Pixhawk® 5X is the latest update to the successful family of Pixhawk® flight controllers, based on the Pixhawk® FMUv5X Open Standard and the Pixhawk® Autopilot Bus Standard. It comes with the latest PX4 Autopilot® pre-installed, triple redundancy, temperature-controlled, isolated sensor domain, delivering incredible performance and reliability.
Inside the Pixhawk® 5X, you can find an STMicroelectronics® based STM32F7, 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® 5X's F7 microcontroller has 2MB flash memory and 512KB RAM. The PX4 Autopilot takes advantage of the increased power and RAM. Thanks to the updated processing power, developers can be more productive and efficient with their development work, allowing for complex algorithms and models.
The FMUv5X open standard includes high-performance, low-noise IMUs on board, designed for better stabilization. Triple redundant IMU & double redundant barometer on separate buses. When the PX4 Autopilot 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 newly designed vibration isolations 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 (LAN8742AI-CZ-TR), high-speed communication with mission computers via ethernet is now supported. Two smart battery monitoring ports (SMBus), support for INA226 SMBus Power module.
The Pixhawk® 5X is perfect for developers at corporate research labs, startups, academics (research, professors, students), and commercial application.
Key Design Points
Modular flight controller: separated IMU, FMU, and Base system connected by a 100-pin & a 50-pin Pixhawk® Autopilot Bus connector, designed for flexible and customizable systems
Redundancy: 3x IMU sensors & 2x Barometer sensors on separate buses, allowing parallel and continuous operation even in the event of a hardware failure
