Holybro SiK 100mW/500mW 433MHZ 915MHZ Telemetry Radio V3 for Pixhawk Flight Controller

The Holybro 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). The radio uses open source firmware which has been specially designed to work well with MAVLink packets and to be integrated with the Mission Planner, Copter, Rover and Plane.
The radios can be either 915Mhz or 433Mhz and you should purchase the model which is appropriate for your country/region.
