Holybro - Pixhawk 6C Mini
by Holybro

The Holybro Pixhawk 6C Mini (Model B, No PMU) is an ultra-compact, high-performance autopilot system built on the Pixhawk FMUv6C open standard and connector standard. Designed for space-constrained and weight-sensitive sUAS setups, this Mini variant packs the exact same high-speed STM32H743 processor (running at 480MHz) and sensor suite as the standard Pixhawk 6C, but condenses the layout and integrates a direct built-in PWM motor/servo header to eliminate messy external breakout wiring. The Model B physical profile features a specialized housing footprint that optimizes internal component spacing and physical ports for demanding miniature flight control applications.

Engineered with an internal vibration isolation system and an onboard temperature-controlled heating array, the Pixhawk 6C Mini delivers flawless sensor telemetry by eliminating high-frequency frame noise and keeping its redundant IMUs at their optimal operational temperature. This specific configuration is supplied as the standalone flight controller module without a Power Management Unit (PMU), offering complete flexibility for advanced drone integrators, university aerospace departments, and tactical drone developers who prefer to use custom power distribution boards (PDBs), dual battery backup systems, or high-voltage UBECs.
