PX4 does not manufacture this (or any) autopilot. Contact the manufacturer for hardware support or compliance issues.
This flight controller has been discontinued and is no longer commercially available.
CUAV v5® (previously "Pixhack v5") is an advanced autopilot designed and made by CUAV®. The board is based on the Pixhawk-project FMUv5 open hardware design. It runs PX4 on the NuttX OS, and is fully compatible with PX4 firmware. It is intended primarily for academic and commercial developers.

- 14路PWM输出 (6路来自FMU, 8路来自 IO)
- Dedicated R/C input for PPM and S.Bus
- 电平/PWM RSSI输入

- 工作温度：-20 ~ 80°C （实测值）
Order from CUAV.
The RCIN interface is limited to powering the rc receiver and cannot be connected to any power/load.
CUAV v5 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 和 POWER2 输入电压 (4.3 v 至 5.4 v)
- USB 输入电压 (4.75 v 至 5.25 v)
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:
The PX4 System 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 CUAV v5 shell. Both ports have standard serial pins and can be connected to a standard FTDI cable (3.3V, but 5V tolerant).
The pinout is as shown.
|针脚||CUAV v5 debug|
|USART2||/dev/ttyS1||TELEM1 (flow control)|
|USART3||/dev/ttyS2||TELEM2 (flow control)|
|USART6||/dev/ttyS4||TX is RC input from SBUS_RC connector|
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.
