CUAV V5 nano Autopilot
V5 nano® is an autopilot for space-constrained applications, designed by CUAV® in collaboration with the PX4 team.
The autopilot is small enough to use in 220mm racing drones, but remains powerful enough for most drone use.
The V5 nano is similar to the CUAV V5+, but has an all-in-one form factor, fewer PWM ports (can't be used for airframes that use AUX ports), and does not have internal damping.

Some of its main features include:
- Full compatibility with the Pixhawk project FMUv5 design standard and uses the Pixhawk Connector Standard for all external interfaces.
- More advanced processor, RAM and flash memory than FMU v3, along with more stable and reliable sensors.
- Firmware-compatible with PX4.
- Generous 2.6mm spacing for for I/O pins, making it easier to use all the interfaces.

Building Firmware
Most users will not need to build this firmware! It is pre-built and automatically installed by QGroundControl when appropriate hardware is connected.
To build PX4 for this target:
make px4_fmu-v5_default
Voltage Ratings
V5 NANO can be Two-fold redundancy on the power supply if two power sources are supplied. The three 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.
