# CUAV V5 nano Wiring Quick Start

注意

PX4 does not manufacture this (or any) autopilot. Contact the manufacturer (opens new window) for hardware support or compliance issues.

This quick start guide shows how to power the CUAV V5 nano flight controller and connect its most important peripherals.

# 接线图概述

The image below shows how to connect the most important sensors and peripherals (except the motor and servo outputs). We'll go through each of these in detail in the following sections.

quickstart

主要接口 功能
电源 Connect Power module; Provides Power and ANALOG voltage and current measurements.
PM2 Do not use with PX4
TF CARD SD card for log storage (comes with card)
M1~M8 PWM输出接口 可以使用它控制电机或舵机。
A1~A3 Capture pins (not currently supported on PX4).
nARMED Indicates the FMU armed state. It is active low (low when armed).
DSU7 用于FMU调试,读取调试信息。
I2C2/I2C3/I2C4 连接I2C总线设备;比如外部指南针。
CAN1/CAN2 用于连接UAVCAN设备,比如CAN GPS。
TYPE-C(USB) Connect to a computer for communication between the flight controller and the computer, such as loading firmware
GPS&SAFETY 连接到Neo GPS,其中包括GPS、安全开关、蜂鸣器接口。
TELEM1/TELEM2 连接到数传电台
DSM/SBUS/RSSI 包含DSM、SBUS、RSSI信号输入接口;DSM接口可以连接DSM卫星接收机,SBUS接口可以连接SBUS总线的遥控器接收机,RSSI连接RSSI信号强度回传模块。

Note For more interface information, please read V5 nano Manual (opens new window).

quickstart

Note If the controller cannot be mounted in the recommended/default orientation (e.g. due to space constraints) you will need to configure the autopilot software with the orientation that you actually used: Flight Controller Orientation.

# GPS + 罗盘 + 安全开关 + LED

The recommended GPS module is the Neo v2 GPS, which contains GPS, compass, safety switch, buzzer, LED status light.

Note 如果无法以推荐/默认方向安装控制器(例如,由于空间限制),则需要以实际使用的方向配置自动驾驶仪参数:飞控的安装方向

The GPS/Compass module should be mounted on the frame as far away from other electronics as possible, with the direction marker towards the front of the vehicle (Neo GPS arrow is in the same direction as the flight control arrow). Connect to the flight control GPS interface using a cable.

NoteIf you use CAN GPS, please use the cable to connect to the flight control CAN interface.

quickstart

# 安全开关

The dedicated safety switch that comes with the V5+ is only required if you are not using the recommended Neo v2 GPS (which has an inbuilt safety switch).

If you are flying without the GPS you must attach the switch directly to the GPS1 port in order to be able to arm the vehicle and fly (If you use the old 6-pin GPS, please read the definition of the bottom interface to change the line).

# 蜂鸣器

If you do not use the recommended Neo v2 GPS the buzzer may not work.

# 遥控器

A remote control (RC) radio system is required if you want to manually control your vehicle (PX4 does not require a radio system for autonomous flight modes). You will need to select a compatible transmitter/receiver and then bind them so that they communicate (read the instructions that come with your specific transmitter/receiver).

The figure below shows how you can access your remote receiver (please find the S.Bus cable in the kit)

quickstart

# Spektrum 卫星接收器

The V5 nano has a dedicated DSM cable. If using a Spektrum satellite receiver, this should be connected to the flight controller DSM/SBUS/RSSI interface.

# 电源

The v5 nano kit includes the HV_PM module, which supports 2~14S LiPo batteries. Connect the 6pin connector of the HW_PM module to the flight control Power interface.

Warning The supplied power module is unfused. Power must be turned off while connecting peripherals.

quickstart

Note The power module is not a power source for peripherals connected to the PWM outputs. If you're connecting servos/actuators you will need to separately power them using a BEC.

# Telemetry System (Optional)

A telemetry system allows you to communicate with, monitor, and control a vehicle in flight from a ground station (for example, you can direct the UAV to a particular position, or upload a new mission).

The communication channel is via Telemetry Radios. The vehicle-based radio should be connected to the TELEM1 or TELEM2 port (if connected to these ports, no further configuration is required). The other radio is connected to your ground station computer or mobile device (usually via USB).

quickstart

# SD 卡

An SD card is inserted in the factory (you do not need to do anything).

# 电机

Motors/servos are connected to the MAIN ports in the order specified for your vehicle in the Airframes Reference.
