CUAV V5+ Autopilot
V5+® is an advanced autopilot manufactured by CUAV®. It was designed by CUAV® in collaboration with the PX4 team.
The autopilot is recommended for commercial systems integration, but is also suitable for academic research and any other use.
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.
- Modular design allows users to customize their own carrier board.
- Built-in vibration dampening system with high performance shock absorption system.
- Multiple-redundant sensor and power systems for improved flight safety and stability.

Voltage Ratings
V5+ AutoPilot can be triple-redundant on the power supply if three power sources are supplied. The three power rails are: POWER1, POWER2 and 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 POWER1, POWER2 or USB or the board will be unpowered.
Normal Operation Maximum Ratings
Under these conditions all power sources will be used in this order to power the system:
- POWER1 and POWER2 inputs (4.3V to 5.4V)
- USB input (4.75V to 5.25V)
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
Debug Port
The system's serial console and SWD interface operate on the FMU Debug port. Simply connect the FTDI cable to the Debug & F7 SWD connector (the product list contains the CUAV FTDI cable). It does not have an i/o debug interface.
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.
