+# CUAV X25-SUPER
+
+<Badge type="tip" text="PX4 v1.18)" />
+
+::: warning
+PX4 does not manufacture this (or any) autopilot.
+Contact the [manufacturer](https://store.cuav.net/) for hardware support or compliance issues.
+:::
+
+The _X25-SUPER_ is an advanced autopilot manufactured by CUAV<sup>&reg;</sup>.
+
+The autopilot is recommended for commercial system integration but is also suitable for academic research and any other applications.
+
+![X25-SUPER AutoPilot - hero image](../../assets/flight_controller/cuav_x25-super/x25-super.png)
+
+The X25-SUPER brings you ultimate performance, stability, and reliability in every aspect.
+
+::: info
+These flight controllers are [manufacturer supported](../flight_controller/autopilot_manufacturer_supported.md).
+:::
+
+### Features
+
+- 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.

+
+## Serial Port Mapping
+
+| UART   | Device     | Port          |
+| ------ | ---------- | ------------- |
+| USART1 | /dev/ttyS0 | GPS1          |
+| USART2 | /dev/ttyS1 | GPS2          |
+| USART3 | /dev/ttyS2 | Debug Console |
+| UART4  | /dev/ttyS3 | UART4         |
+| UART5  | /dev/ttyS4 | TELEM2        |
+| USART6 | /dev/ttyS5 | RC            |
+| UART7  | /dev/ttyS6 | TELEM1        |
+
+## RC Input
+
+The RC input pin is directly connected to the FMU UART6 TX.
+
+## Voltage Ratings
+
+The _X25-SUPER_ 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:
+
+1. **POWER C1** and **POWER C2** Inputs (10V to 18V)
+2. USB Input (4.75V to 5.25V)
+
+**Voltage monitoring**
+
+Digital DroneCAN/UAVCAN battery monitoring is enabled by default.
+
+## Building Firmware
+
+::: tip
+Most users will not need to build this firmware from PX4 v1.18.
+It is pre-built and automatically installed by _QGroundControl_ when appropriate hardware is connected.
+:::
+
+To [build PX4](../dev_setup/building_px4.md) for this target, execute:
+
+```
+make cuav_x25-super_default
+```
+
+## Debug Port {#debug_port}
+
+The [PX4 System Console](../debug/system_console.md) and [SWD Interface](../debug/swd_debug.md) operate on the **FMU Debug** port.
+
+| Pin     | Signal         | Volt  |
+| ------- | -------------- | ----- |
+| 1 (red) | 5V+            | +5V   |
+| 2 (blk) | DEBUG TX (OUT) | +3.3V |
+| 3 (blk) | DEBUG RX (IN)  | +3.3V |
+| 4 (blk) | FMU_SWDIO      | +3.3V |
+| 5 (blk) | FMU_SWCLK      | +3.3V |
+| 6 (blk) | GND            | GND   |
+
+## Supported Platforms / Airframes
+Any multicopter / airplane / rover or boat that can be controlled with normal RC servos or Futaba S-Bus servos.
