Pixhawk 5X Holybro Overview

Inside the Pixhawk 5X Holybro, 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 drone Autopilot flight controllers 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

• 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

• Automated sensor calibration eliminating varying signals and temperature

• IMUs are temperature-controlled by onboard heating resistors, allowing optimum working temperature of IMUs

• Two smart batteries monitoring on SMBus

• Additional GPIO line and 5V for the external NFC reader

• Secure element for secure authentication of the drone (SE050)
