Holybro Pixhawk 6C Flight Controller

The Holybro Pixhawk 6C is an industrial-grade H7-based autopilot designed for commercial, enterprise, and research applications. Powered by the STM32H743 processor, it provides the computational bandwidth needed for resource-heavy ArduPilot and PX4 builds, ranging from heavy-lift multirotors and VTOLs to fixed-wing aircraft and autonomous rovers.

Key features

• Driven by the 480MHz STM32H743 Cortex-M7 processor for high-speed, demanding control loops

• Triple redundant IMUs (ICM-42688-P, BMI088, ICM-42670-P) and dual barometers ensure robust sensor data

• Supports up to 16 PWM outputs for managing complex airframes, multi-axis gimbals, and payload releases

• Expansive connectivity with dual CAN buses, six UARTs, and dual I2C ports for peripheral expansion

• Built-in sensor vibration isolation mitigates resonance to guarantee stable flight performance out of the box
