This DH-Research NDAA-compliant Telemetry Radio (915Mhz) is a small, light and inexpensive open source radio platform that typically allows ranges of better than 300m “out of the box” (the range can be extended to several kilometers with the use of a patch antenna on the ground). This radio is plug-n-play all Pixhawk Standard and other Flight Controller, providing the easiest ways to setup a telemetry connection between your Autopilot and a ground station. It uses open source firmware which has been specially designed to be integrated with the Ardupilot, Mission Planner, and QGroundControl.
Assembled in Taiwan.
