Holybro Pixhawk 6X (ICM-45686) Flight Controller

Key Design Points

• Redundancy: 3x ICM-45686 IMU sensors (±32g) with BalancedGyro™ technology & 2x Barometer sensors

• High-performance STM32H753 Processor with a clock speed of up to 480 MHz

• Modular flight controller: separated IMU, FMU, and Base system connected by a 100-pin & a 50-pin Pixhawk® Bus connector.

• Triple redundancy domains: Completely isolated sensor domains with separate buses and separate power control

• All-New advanced durable vibration isolation material with resonance frequency in the higher spectrum

• Ethernet interface for high-speed mission computer integration. Transformerless can be achieved using 50 Ohm termination resistors at the target device (AN2190 50 Ohm termination).

• Temperature-controlled IMU board, allowing the optimum working temperature of IMUs

• Hardware switchable 3.3V or 5V signal mode (requires baseboard modification)

• Digital power module support for better voltage and current data accuracy

All new Vibration Isolation Design

This new vibration isolation design uses the same custom-formulated durable isolation material as the Pixhawk 6X Pro, instead of the traditional foam design. Backed by extensive R&D and testing, it offers optimal IMU damping characteristics with a resonance frequency in the higher spectrum, perfect for industrial and commercial drones.

Note: 

• The Rev 8 Version is supported in the PX4 1.14.3 release or later, as well as the Ardupilot 4.5.0 stable release or later. It ships with PX4 firmware by default. The user can also use the Ardupilot firmware by flashing the firmware via Mission Planner or QGroundControl.
