V5 nano AutoPilot
V5 nano® is an autopilot for space-constrained applications manufactured by CUAV®. It is based on the Pixhawk FMUv5 design standard and is compatible with PX4 firmware and ArduPilot firmware. The autopilot combines small size with powerful features, and can be used not only in ordinary drones, but also 220mm racing drones and other space limited vehicles.
Main FMU Processor: STM32F765◦32 Bit Arm® Cortex®-M7, 216MHz, 2MB memory, 512KB RAM

- 4 I2C ports
- 4 SPI buses
- 2 CANBuses
- Analog inputs for voltage / current of battery
- 2 additional analog input
- Power System:
- Power Brick Input: 4.75~5.5V
- USB Power Input: 4.75~5.25V
- Servo Rail Input: 0~36V
- Weight and Dimensions:
- Dimensions: 60*40*14mm
- Other Characteristics:
- Operating temperature: -20 ~ 85°c（Measured value）
[!NOTE] Run Ardupilot firmware, A1~A3 can be used as PWM output interface. Run PX4 firmware, A1~A3 can be used as PWM/capture input. The nARMED interface only supports PX4 firmware.
[!TIP] DSU7 is a new interface for CUAV naming, including fmu swd and uart7 interfaces. When V5+ runs PX4 firmware, uart7 is used as the DEBUG interface, PM2 does not work; when running ArduPilot firmware; uart7 is used as the communication serial port and usb is Used to debug the output, PM2 works.
[!Warning] The PPM IN interface is limited to powering the rc receiver and cannot be connected to any power/load.

V5 nano can be Two-fold redundancy on the power supply if two power sources are supplied. The two power rails are: POWER1and USB. The output power rails FMU PWM OUT and I/O PWM OUT (0V to 36V) do not power the flight controller board (and are not powered by it). You must supply power to one of POWER1or USB or the board will be unpowered. The PM2 connector only works with Ardupilot firmware and can only detect battery voltage and current, not powering V5 nano.
Supported Platforms / Airframes
Any multicopter / airplane / rover or boat that can be controlled with normal RC servos or Futaba S-Bus servos. The complete set of supported configurations can be seen in the Airframes Reference (PX4 firmware click here, Ardupilot firmware click here).
