ZeroOne X6 Ultra FMU v6X Autopilot Flight Controller, Triple-IMU, Gigabit Ethernet, ArduPilot/PX4 for Heavy-Lift Drone

Overview

The ZeroOne X6 Ultra Autopilot Flight Controller is designed for high-end and large UAV platforms, using a tactical-grade IMU sensor stack for high dynamic range, strong vibration resistance, low noise, and low-bias stability. It features an upgraded IMU temperature-compensation heating system (+100% heating power), a built-in vibration isolation structure, and a Gigabit Ethernet port for advanced companion-computer applications. Built on the open-source FMU v6X hardware standard, X6 Ultra offers rich interfaces and reliable performance for challenging environments, including GPS-denied operation and heavy-load aircraft.
