915MHz 500mW Telemetry Kit

Establish a robust MAVLink connection between your ground control station and UAV with this 915MHz 500mW Telemetry Kit. Designed for ArduPilot and PX4 builds, this bidirectional datalink replaces standard RC telemetry with a dedicated data stream. The 500mW (27dBm) output ensures reliable long-range communication, making it highly suited for agricultural drones, autonomous fixed-wings, and heavy-lift multirotors mapping large areas.

Key features

• 500mW (27dBm) transmit power for extended range and strong signal penetration.

• Bidirectional datalink tailored specifically for MAVLink communication.

• Pre-flashed with open-source SiK firmware for plug-and-play operation.

• Two transceivers: one connects to the flight controller over UART, the other to a PC or OTG tablet over USB.
