433Mhz 100mW Radio Telemetry Kit

The 433MHz 100mW SiK Telemetry Kit is a compact, high-quality telemetry solution designed for reliable communication between your drone and ground station. Based on HopeRF HM-TRP modules and SiK firmware, this Telemetry Kit provides a transparent serial link for seamless data exchange between flight controllers such as Pixhawk and Ardupilot and ground station software like Mission Planner. Featuring MAVLink protocol framing, frequency hopping spread spectrum (FHSS), and adaptive time division multiplexing, it ensures stable and interference-resistant telemetry connection during mission-critical operations.

Built for flexibility, this kit includes interchangeable air and ground modules, each equipped with a Micro-USB port, serial interface, and RP-SMA connector for easy integration with various setups. Whether you are operating a Plane, Copter, or Rover, the 433MHz band and 20dBm transmit power provide excellent Range for small to medium UAV platforms. The antenna options, including omni antenna and patch antenna, enhance link stability, and error correction improves data integrity even in demanding environments.

This telemetry solution is ideal for drone builders, FPV project enthusiasts, and operators using Autopilot systems like Ardupilot Pixhawk or Pixhawk Standard. With proven reliability in field tests and configuration support via Mission Planner and AT commands, it’s a trusted component for both DIY and professional UAV builds.
