CUAV X25 EVO Autopilot Flight Controller - STM32H7, Triple IMU, Dual Baro, RM3100, CAN, 16 PWM, PX4/ArduPilot

Overview

CUAV X25 EVO is a high-reliability core controller for unmanned systems. It combines an STM32H7 (480 MHz, 2 MB Flash) processor with a triple industrial-grade IMU array, dual barometers, and RM3100 magnetometers. A redesigned power architecture supports 10–18 V input and provides up to 5 V/12 A external output to power heavy payloads. The controller integrates dual-path power redundancy, comprehensive ESD/over-current protection, RGB status indication, and a modular CORE/carrier design. It is compatible with ArduPilot and PX4, and suits multirotors, fixed-wing, VTOL, helicopters, UGV/USV/UUV and other platforms.

Key Features

• High-performance compute: STM32H7 @ 480 MHz, 2 MB Flash; low CPU usage headroom for advanced algorithms (non-GPS nav, FFT filters, LUA scripts).

• Industrial sensor suite:

  • IMUs: 2× TDK IIM-42653 (±4000 °/s, ±32 g) + 1× TDK IIM-42652 (±2000 °/s, ±16 g).

  • Magnetometers: PNI RM3100 (anti-interference).

  • Barometers: TDK ICP20100 & Bosch BMP581 (dual).

  • Heterogeneous IMU matrix with fault-tolerant switching.

• Dual-temperature-compensation system for the IMU: real-time compensation ±0.5 °C; vs. prior generation—15% lower temp drift, 25% better attitude solution consistency.

• Vibration isolation: 4th-gen inclined symmetric nylon matrix damping; optional external fixed-ear isolators to suppress abnormal high-frequency vibration and improve data fidelity.

• Power architecture: onboard 5 V/15 A high-power DC-DC; external port supports 5 V/12 A output; input range 10–18 V.

• Networking & buses: CAN bus (smart battery/ESC/servos, telemetry feedback) + 100 M Ethernet.

• Abundant I/O: up to 16 PWM via servo ports; up to 32 PWM through CAN expansion.

• Ruggedization & QA: dual-channel power redundancy, ESD & over-current protection, anti-static connector design, PCB conformal coating, and fully automated testing.

• RGB status indicator: multi-color LEDs for arming, power, GNSS/position, fault modes, etc.
