Holybro Pixhawk 6X Autopilot Pixhawk Flight Controller (ICM-45686)

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 durabile silicone-based 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.
