Holybro Pixhawk 6C with Aluminum Case
by Holybro

The Holybro Pixhawk 6C with Aluminum Case is a premium, cost-effective autopilot system precision-engineered for autonomous drones, unmanned ground vehicles (UGVs), robotic platforms, and advanced academic research. Built upon the official Pixhawk FMUv6C open standard and connector framework, this version features a rugged, CNC-machined aluminum housing that provides superior electromagnetic interference (EMI) shielding, exceptional thermal dissipation, and industrial-grade mechanical protection. Shipped pre-installed with the industry-standard PX4 Autopilot firmware (and fully compatible with ArduPilot), the Pixhawk 6C delivers a robust dual-redundant architecture tailored for commercial Beyond Visual Line of Sight (BVLOS) mapping, automated agricultural surveying, and heavy-payload enterprise missions.

At its core, the system utilizes a high-performance STMicroelectronics STM32H743 processing core. Housing a 32-bit Arm Cortex-M7 microprocessor clocked up to an explosive 480MHz, it comes equipped with 2MB of flash memory and 1MB of SRAM, giving developers the computational overhead required to execute complex custom control algorithms, heavy onboard scripts, and real-time flight models effortlessly. It is paired with an independent STM32F103 input/output processor running at 72MHz to safely manage peripheral communication, signal sorting, and fail-safe safety overrides.

To guarantee mission reliability, the flight controller features internal sensor redundancy driven by state-of-the-art IMUs from Bosch and InvenSense. These sensors are integrated directly into a newly designed internal mechanical vibration-damping frame that filters out high-frequency motor and prop wash resonance. Furthermore, the onboard IMUs are temperature-controlled via integrated hardware heating resistors, keeping the sensors locked into their optimal operating temperatures to neutralize sensor drift and calibrate accurate attitude data in sub-zero alpine conditions or scorching desert heat.
