3DR RADIOV2

QUICK START GUIDE

PARTS

GETTING STARTED

3DR Radios provide an air-to-ground data link between the autopilot and your ground station laptop or

tablet. Follow this guide to install the radios on your plane, copter, or rover. 3DR Radios arrive ready to

use. Just mount and connect to view real-time data from your drone.

Android adapter cable

6-wire Pixhawk connector cable

Micro-USB cable

Two 3DR Radios in 915 or 433 mHz Attach the antennas, and use either radio as an air or ground module.

6-to-5-position APM and PX4 connector cab
MOUNT

CONNECT TO AUTOPILOT

Connect to the APM 2.5 or 2.6 telemetry port using

the 6-to-5-position cable.

Connect to the PX4 I/O telemetry

port using the 6-to-5-position cable. Connect to the Pixhawk telemetryport using the 6-wire cable.

Mount the air module securely to your vehicle keeping the antenna clear of any propellers or moving

components. Ensure that the antenna is oriented vertically for maximum range. CONNECT TO MISSION PLANNER

Use the micro-USB cable to connect the ground module to your laptop. In Mission Planner and APM

Planner ground station applications, select the communication option that shows COM, set the rate

to 57600, and select Connect. The radio will not connect unless the vehicle is powered. Use the Flight

Data screen to view your vehicle’s status and control missions in flight.

TIPS

Orient the ground radio

antenna vertically for maximum range. CONNECT TO TABLET

Connect the ground module to your tablet using the Android adapter cable. Connect the colored end

to the tablet and the black end to the radio. In DroidPlanner or Andropilot, select Connect.

SETTINGS

To change the radio settings in the mission planner, connect the radio to your computer, but do not select Connect. Radios can only be configured while unconnected to MAVLink. Select Initial Setup, 3DR Radio, and Load Settings to configure the radios.

All settings should be the same for both modules. Ensure that the Net ID setting is identical on each

radio to enable pairing. Select Save Settings to apply settings. For flying with friends, make sure your Net IDs do not conflict. Use the configuration options on this screen to apply the correct airspace regulation requirements

for your area. You are responsible for complying with all airspace regulations in your area, including

frequency restrictions, power levels, and licenses. For more information on configuring 3DR Radios to

comply with local regulations, visit the online documentation at goo.gl/Tsrksf.
