Product overview
The CUAV X25 MEGA Flight Controller provides control and sensor processing for industrial unmanned systems, including multirotor and fixed-wing aircraft, unmanned ships and robots. Its architecture combines a 480 MHz STM32H7 processor with three accelerometer/gyroscope devices, two barometers and an RM3100 electronic compass. A detachable CORE module supports modular expansion. The controller measures 76.5 × 45.45 × 32.2 mm and weighs 108.5 g, giving integrators concrete dimensions and mass for installation planning.
Integration interfaces include two GPS ports, two telemetry ports, Ethernet, CAN, I2C, SPI6 and USB Type-C, alongside RC input and analogue connections. Actuator integration supports 16 PWM outputs through the Servo port and 32 through CAN, with selectable 3.3 V or 5 V PWM levels. The 100M Ethernet interface supports expansion to onboard computers, optical cameras and data links. ArduPilot and PX4 compatibility provides an established software integration route, while CAN carries connected-device status and operating information.
Configuration choices include versions with and without a power module; PMU 2 Lite is the specified standard module. Supply requirements differ by connection: USB accepts 4.75–5.25 V, PMU 2 Lite accepts 20–70 V, and the Power input accepts 10–18 V. The operating temperature range is -20 to +85 °C. Conformal-coated circuitry, multidirectional damping and coordinated IMU and motherboard temperature control address environmental exposure and sensor stability. Purchase and use terms restrict the equipment to legal civilian purposes and prohibit military or weapons-related use.
