Order from CUAV.
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 RCIN interface is limited to powering the rc receiver and cannot be connected to any power/load.
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 PX4 Firmware

Building ArduPilot Firmware
./waf configure --board CUAVv5
./waf copter --upload
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. To access the I/O Debug port, the user must remove the V5-AutoPilot shell. Both ports have standard serial pins and can be connected to a standard FTDI cable (3.3V, but 5V tolerant) or [Dronecode probe]. Dronecode probe.
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.
