Key Design Points
Redundancy: 3x ICM-45686 IMU sensors (±32g) with BalancedGyro™ technology & 2x Barometer sensors
High performance STM32H753 Processor with clock speed up to 480 MHz
Modular flight controller: separated IMU, FMU, and Base system  connected by a 100-pin & a 50-pin Pixhawk® Autopilot 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
Temperature-controlled IMU board, allowing optimum working temperature of IMUs
All new Vibration Isolation Design
This new vibration isolation design uses same custom-formulated durable isolation material as the Pixhawk 6X Pro, in place of the traditional foam design.    Backed by extensive R&D and testing, it offers optimal IMU damping characteristics with resonance frequency in the higher spectrum, perfect for industrial and commercial drone

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.    User can also use Ardupilot firmware by flashing the firmware via Mission Planner or QGroundControl.
