RFDesign RFD868x Telemetry Modem Bundle
by RFDesign

The RFDesign RFD868x Telemetry Modem Bundle provides ultra-long-range, high-speed data communication for UAVs, drones, robotics, and remote telemetry systems. This bundle includes two pre-configured RFD868x modems and all necessary accessories for plug-and-play integration. With a powerful 1 W transmit output, AES-128 encryption, and air data rates up to 500 kbps, this modem delivers reliable, secure, and efficient telemetry over distances exceeding 40 km line-of-sight.

The RFD868x uses a 32-bit ARM processor running SiK firmware, supporting MAVLink, frequency hopping, DSSS, and antenna diversity for consistent performance. Included antennas and FTDI USB cable simplify setup and ensure strong signal quality. Whether you're flying long missions, managing remote sensors, or automating a fleet, the RFD868x bundle is built for dependable communication in demanding environments.
