Holybro Pixhawk 6C Mini Flight Controller

The Holybro Pixhawk 6C Mini is a compact autopilot built on the Pixhawk FMUv6C open standard, sharing the STM32H743 processor and sensor set of the full-size Pixhawk 6C. A built-in PWM header replaces some of the 6C's ports to save space, which suits small multirotors, VTOLs, fixed-wings and research airframes running PX4 or ArduPilot.

Key features

• STM32H743 Cortex-M7 at 480 MHz with 2 MB flash and 1 MB RAM, backed by an STM32F103 IO co-processor
• Redundant ICM-42688-P and BMI088 IMUs on a vibration-isolation system
• Onboard MS5611 barometer and IST8310 magnetometer
• 14 PWM servo outputs (8 from IO, 6 from FMU), two CAN buses and two GPS ports
• Model A and Model B differ in which way the pin header faces, for flexible installation; Model A is the revised board with a steadier PWM signal under load
