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 application scenarios:
It can be used as an UAS equipment development board hardware for scientific research and can also be written into PX4/arduPilot programs. It is applicable to and not limited to the following frameworks:
- Rover(including lawn mowers, agricultural sprayers, express delivery vehicles, etc.)
- Unmanned ships
- Unmanned submarines
- UAV/Drone (Various shapes and specifications of heilcopter, copter, plane, VTOL, etc.)
- Robots

connection

[!TIP] DSU7 is a new interface named by CUAV, including fmu swd and uart7 interface. When V5+ runs PX4 firmware, uart7 is used as DEBUG interface, when running ArduPilot firmware; uart7 can be used as a normal serial port, USB is used for debug output.

Voltage Ratings
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 (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.
Peripherals
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).
