Holybro Telemetry Radio V3

This Holybro SiK Telemetry Radio is a small, light and inexpensive open source radio platform that typically allows ranges of better than 300 m “out of the box” (the range can be extended to several kilometers with the use of a patch antenna on the ground).

This Telemetry Radio V3 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 work well with MAVLink packets and to be integrated with the Mission Planner, Ardupilot, QGroundControl, PX4 Autopilot.

The radios can be either 915Mhz or 433Mhz and you should purchase the model which is appropriate for your country/region.
