CUAV X25-EVO 
WARNING
PX4 does not manufacture this (or any) autopilot. Contact the manufacturer for hardware support or compliance issues.
The X25-EVO is an advanced autopilot manufactured by CUAV®.
The autopilot is recommended for commercial system integration but is also suitable for academic research and any other applications.

The X25-EVO brings you ultimate performance, stability, and reliability in every aspect.
INFO
These flight controllers are manufacturer supported.
特性 
- Arm® Cortex-M7® processor (STM32H743XI) with Floating-Point Unit (FPU), operating at 480MHz, and featuring 2MB Flash memory. Enables developers to enhance productivity and efficiency, allowing for more complex algorithms and models.
- Automotive-grade RM3100 compass. Designed for better stability and anti-interference capability.
- Triple-redundant IMUs and dual-redundant barometers located on separate buses. If the PX4 autopilot detects a sensor failure, the system seamlessly switches to another sensor to maintain flight control reliability.
- Independent LDO power control supplies power to each sensor group. A vibration isolation system filters high-frequency vibrations and reduces noise to ensure accurate readings, enabling better overall flight performance for the vehicle.
- Integrated Microchip Ethernet PHY for high-speed communication with onboard devices like mission computers via Ethernet.
- Dual temperature compensation systems, located on the IMU board and FMU board respectively. Temperature is controlled by onboard heating resistors to achieve the optimal operating temperature for the IMUs.
- PWM servo output voltage switchable between 3.3V or 5V.
- Modular design for DIY carrier boards.

额定电压 
The X25-EVO achieves triple redundancy on power supplies if three power sources are provided. The three power rails are POWERC1, POWERC2, and USB.
- POWER C1 and POWER C2 are DroneCAN/UAVCAN battery interfaces.
Normal Operation Maximum Ratings
Under these conditions, all power sources will be used to power the system in the following order:
- POWER C1 and POWER C2 Inputs (10V to 18V)
- USB Input (4.75V to 5.25V)
Voltage monitoring
Digital DroneCAN/UAVCAN battery monitoring is enabled by default.

TIP
Most users do not need to build this firmware! It is pre-built and installed automatically by QGroundControl when the appropriate hardware is connected.
To build PX4 for this target, execute:
make cuav_x25-evo_default调试接口 
The PX4 System Console and SWD Interface operate on the FMU Debug port.
