V5+ AutoPilot

V5+® is an advanced autopilot manufactured by CUAV®. The board is based on the Pixhawk FMUv5 design standard, the external interface uses the Pixhawk standard pinouts, and the modular design allows the users to customize their own carrier board. The autopilot is compatible with both PX4 and ArduPilot firmware.V5+ is ideal for academic research and commercial systems integration.

connection

V5+ AutoPilot 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; when running ArduPilot firmware; uart7 is used as the communication serial port and usb is used to debug the output.

The PPMIN interface is limited to powering the rc receiver and cannot be connected to any power/load.

Voltage Ratings

V5+ AutoPilot can be triple-redundant on the power supply if three power sources are supplied. The two 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:

  1. POWER1 and POWER2 inputs (4.3V to 5.4V)
  2. USB input (4.75V to 5.25V)

Building PX4 Firmware

make px4fmu-v5_default upload

Building ArduPilot Firmware

./waf configure --board CUAVv5

./waf copter --upload

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

  • Digital Airspeed Sensor
  • Telemetry Radio
  • Rangefinders/Distance sensors
  • others

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).
