# 3DR RADIO V2 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.

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.

# 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 Settingsto 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 Settingsto 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.
