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

Wiring Chart Overview

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.


Main interface Function
POWER1 Connect Power module; power input & AD voltage and current detection
PM2 Do not use with PX4, but ardupilot firmware can be supported.
TF CARD Insert SD card for log storage
M1~M8 PWM outputs,Can be used to control motors or servos
A1~A8 PWM outputs,Can be used to control motors or servos
DSU7 Used for FMU debug, reading debug information
I2C2/I2c3/I2c4 Connect an I2C device such as an external compass
CAN1/CAN2 Connect UAVCAN devices such as CAN GPS
TYPE-C(USB) Connect to a computer for communication between the flight controller and the computer, such as loading firmware
GPS&SAFETY Connect to Neo Gps, which includes GPS, safety switch, buzzer interface
TELEM1/TELME2 Connect to the Telemetry System
DSM/SBUS/RSSI Includes DSM, SBUS, RSSI signal input interface, DSM interface can be connected to DSM satellite receiver, SBUS interface to SBUS remote control receiver, RSSI for signal strength return module

[!TIP] For more interface information, please read V5 nano Manual.


[!NOTE] If the controller cannot be mounted in the recommended/default orientation (e.g. due to space constraints) you willneed to configure the autopilot software with the orientation that you actually used:Flight Controller Orientation(PX4 firmware click here, Ardupilot firmware click here).

GPS + Compass + Safety Switch + LED

The recommended GPS modules are the neo v2 GPS, It contains GPS, compass, safety switch, buzzer, LED status light. 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.

[!TIP] If you use CAN GPS, please use the cable to connect to the flight control CAN interface.。


Safety Switch

The dedicated safety switch that comes with the V5+ is only required if you are not using the recommended NEO 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.).


If you do not use the recommended GPS, there may be problems with the buzzer not working. You may need to add an external buzzer instead.

Radio Control

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 sbus cable in the kit)



The v5 nano kit includes HV_PM, which supports 2~10s lipo battery. Please connect the 6pin connector of the HW_PM module to the flight control power1 interface.


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/TELEM2 port (if connected to this port, no further configuration is required). The other radio is connected to your ground station computer or mobile device (usually via USB).


SD Car(Optional)

The factory has completed inserting the sd card, you do not need to operate.


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