Overview

This Holybro SiK Telemetry Radio 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 kilometres with the use of a patch antenna on the ground). This radio is plug-n-play, ready for all Pixhawk Standard and other flight controllers, providing the easiest way to set up a telemetry connection between your Flight Controller and a ground station. It uses open-source firmware that has been specially designed to work well with MAVLink packets and to be integrated with the Mission Planner, Ardupilot, QGroundControl, PX4, and Flight Controller. The radios can be either 915 MHz or 433 MHz, and you should purchase the model that is appropriate for your country/region.
