CUAV v5

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

# 额定电压

CUAV v5 can be triple-redundant on the power supply if three power sources are supplied. 三个电源口:POWER1, POWER2 and USB

Note 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.

正常运行最大额定值

在这些条件下,所有电源将按此顺序用于为系统供电:

  1. POWER1POWER2 输入电压 (4.3 v 至 5.4 v)
  2. USB 输入电压 (4.75 v 至 5.25 v)

# 编译固件

Tip 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调试端口

The PX4 System Console and SWD interface operate on the FMU Debug port. 只需将FTDI电缆连接到Debug & F7 SWD连接器。 To access the I/O Debug port, the user must remove the CUAV v5 shell. 这两个端口都有标准串行引脚, 可以连接到标准的FTDI电缆(3.3 v,但耐压5v )。

引脚排列如图所示
