HolyBro Pixhawk 6X (ICM-45686) / Pixhawk 6X Pro Flight Controller Module for RC FPV Drone

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® 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. 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

• 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 drone
