Pixhawk 6C Mini Model-A

The Holybro Pixhawk 6C Mini Model-A is a compact high-performance autopilot flight controller designed for professional UAVs, multirotors, fixed-wing aircraft, VTOL platforms, autonomous vehicles, and robotic systems.

Based on the Pixhawk FMUv6C Open Standard, it combines a powerful STM32H743 processor, redundant inertial sensors, integrated vibration isolation, extensive connectivity, and a built-in PWM output header in a compact form factor.

The current Model-A version also provides improved PWM signal stability under load for reliable servo and actuator control.

Powerful STM32H743 Processor

The Pixhawk 6C Mini Model-A is powered by an STM32H743 Arm Cortex-M7 processor operating at up to 480 MHz.

With 2 MB Flash memory and 1 MB RAM, it provides the processing capability required for advanced flight control algorithms, autonomous navigation, sensor fusion, telemetry systems, and complex UAV applications.

A dedicated STM32F103 I/O processor manages real-time input and output functions.

Redundant Inertial Measurement System

The flight controller integrates two independent IMUs:

ICM-42688-P accelerometer and gyroscope
BMI088 accelerometer and gyroscope

This redundant sensor architecture improves system reliability and provides accurate motion data for demanding autonomous flight applications.

Integrated Vibration Isolation

The Pixhawk 6C Mini features an integrated vibration isolation system designed to reduce high-frequency vibration and sensor noise.

This helps improve IMU measurement quality, flight stability, and overall navigation performance.

Temperature-Controlled IMUs

The onboard inertial sensors are temperature-controlled using integrated heating resistors.

Maintaining the IMUs within an optimized operating temperature range helps improve sensor consistency and performance across changing environmental conditions.

Compact Model-A Design

The Model-A version provides the processing capability and sensor architecture of the standard Pixhawk 6C in a significantly smaller form factor.

Its compact housing and integrated PWM header simplify installation in UAV platforms where available space is limited.

Improved PWM Signal Stability

The current Model-A version features an updated design that provides a more stable PWM signal under load.

This improves signal reliability when controlling servos, ESCs, actuators, and other PWM-compatible equipment.

Integrated Navigation Sensors

The Pixhawk 6C Mini Model-A includes an onboard MS5611 barometer for altitude measurement and an IST8310 magnetometer for heading information.

External GNSS modules, compasses, airspeed sensors, rangefinders, and additional navigation peripherals can be connected through the available interfaces.

14 Integrated PWM Outputs

The flight controller provides 14 PWM servo outputs:

8× I/O PWM outputs
6× FMU PWM outputs

The integrated PWM header allows direct connection of ESCs, servos, and actuators without requiring a separate external PWM breakout board.

PWM signal voltage can be configured to 3.3 V or 5 V through an internal hardware modification.

Dual CAN Bus Support

Two CAN buses support the integration of DroneCAN-compatible devices.

Compatible peripherals may include GNSS modules, compasses, power modules, airspeed sensors, rangefinders, and other professional UAV equipment.

Multiple GPS & Telemetry Interfaces

The Pixhawk 6C Mini Model-A includes two GPS ports.

GPS1 provides a complete GPS interface with safety switch support, while GPS2 provides an additional GPS connection for redundant or multi-GNSS configurations.

Two telemetry ports with hardware flow control provide connectivity for telemetry radios, datalinks, companion computers, and additional serial peripherals.

PX4 & ArduPilot Compatibility

The Pixhawk 6C Mini Model-A ships with PX4 FMUv6C firmware and also supports ArduPilot.

It is suitable for commercial UAV development, autonomous robotics, academic research, prototyping, testing, and professional aircraft integration.
