HolyBro SiK Telemetry Radio V3 500mW 915MHz

HolyBro SiK Telemetry Radio V3 500mW 915MHz

Overview

The HolyBro SiK Telemetry Radio is a lightweight and affordable open source radio platform that provides range beyond 300m, typically out of the box; it can be extended to several kilometers when using a patch antenna.
This radio provides a plug-and-play method to establish a telemetry link between Pixhawk standard and other flight controllers, autopilots and a ground station. It uses open source software specifically designed to work well with MAVLink packages and integrate with mission planners, Ardupilot, QGroundControl and PX4 Autopilot.
The radio can be on 915MHz or 433MHz frequencies and the appropriate model for your country/region should be purchased.

Note: This radio does not support software installation via Mission Planner 1.3.75 or earlier. If software installation is required, use Mission Planner 1.3.75.1 or later.
