## Description

433MHz, 100mW radio telemetry set, for stable bidirectional communication between the drone and the ground station, plug and play compatible with Pixhawk Standard and other controllers. Runs SiK open source firmware optimized for MAVLink, easily integrates with Mission Planner, Ardupilot, QGroundControl and PX4, offers full duplex link with FHSS and error correction, with a range of over 300 m out of the box.
Holybro SiK telemetry set that operates at a frequency of 433MHz, with a maximum power of 100mW. This is an open-source, compact and lightweight radio platform that facilitates bidirectional communication between the drone's autopilot and the base station on the ground. It offers a plug-and-play connection for compatible Pixhawk Standard flight controllers and other types of controllers, being easy to configure for remote monitoring and control.
The module uses SiK open-source firmware, specially designed to work efficiently with MAVLink packages and to integrate perfectly with software such as Mission Planner, Ardupilot, QGroundControl and PX4 Autopilot.
It has a maximum output power of 100 mW and a reception sensitivity of -117 dBm, this telemetry set allows a range of over 300 meters "out of the box", and with a patch antenna, this distance can be significantly extended .
