Holybro - Pixhawk 6C Mini Model A (FC Only)
by Holybro

Product Description

The Holybro Pixhawk 6C Mini Model A (FC Only) is a compact, dual-redundant autopilot flight controller built on the open-source Pixhawk FMUv6C standard. Powered by an STMicroelectronics STM32H743 main processor running at 480MHz alongside an STM32F103 I/O co-processor, the Pixhawk 6C Mini packs high-performance processing, redundant IMU sensor arrays, and a built-in PWM servo rail into an extra-small form factor.

Featuring an internal vibration-isolation suspension system and temperature-controlled IMU heating elements, the 6C Mini isolates sensors from high-frequency frame vibrations to deliver precise state estimation in challenging flight environments. The Model A revision features an upgraded PWM signal architecture that maintains signal stability under heavy electrical loads, making it an ideal choice for research, corporate labs, micro autonomous aircraft, multirotors, and unmanned surface or ground vehicles.

Key Features

• STM32H743 FMU Processor: High-speed 480MHz Arm Cortex-M7 core with 2MB flash and 1MB RAM for handling complex flight algorithms and autonomous control tasks.

• Redundant IMU Array & Heating: Combines InvenSense ICM-42688-P and Bosch BMI088 sensors with integrated heating resistors to maintain optimal working temperatures.

• Integrated Vibration Isolation: Internal mechanical dampening filters high-frequency motor and prop noise, preventing gyro noise from degrading flight performance.

• Built-in PWM Servo Header: Provides direct access to 14 PWM outputs (8 I/O + 6 FMU) without requiring external breakout boards.

• Model A Signal Stability: Revised Model A hardware architecture provides consistent, stable PWM signaling under heavy electrical loads.

• PX4 & ArduPilot Native Support: Fully supported by open-source PX4 Autopilot and ArduPilot flight stack firmwares.
