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 cable
MOUNT
CONNECT TO AUTOPILOT
Connect to the APM 2.5 or 2.6 telemetry port using
the 6-to-5-position cable.
2.6
Connect to the PX4 I/O telemetry
port using the 6-to-5-position cable.
Connect to the Pixhawk telemetry
port 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.

about installing a mission planner application for your laptop or tablet and interacting with the
autopilot using 3DR Radios (including retrieving flight data logs) at planner.ardupilot.com.
Mission Planner
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.
DroidPlanner Flight Data screen
View the strength of the radio signal in the
mission planner’s flight data screen.
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.
