Bundle RFD868x Telemetry Modem Kit
Important: check local radio regulations before use.
The RFD868x is a radio transmitter for system integrators. The user is responsible for checking whether the selected frequency, output power, and application comply with local regulations.
The Bundle RFD868x is a long-range telemetry modem kit for UAVs, drones, robotics, and remote data communication. It includes two RFD868x radio modems, multiple antennas, and an FTDI USB cable for setup and configuration.
The RFD868x is designed for reliable telemetry links in professional drone operations, long-range UAV projects, and advanced system integration. It supports SiK-based firmware, configurable data rates, antenna diversity, and up to 1 W transmit power.
Key Features
- Long-range telemetry modem – Suitable for UAV telemetry, drone control, robotics, and remote data links.
- Two RFD868x modems included – Build a complete radio link between vehicle and ground station.
- 868-869 MHz frequency range – Designed for long-range communication applications in the 868 MHz band.
- 1 W transmit power – Up to +30 dBm output power, configurable in 1 dB steps.
- Diversity antenna support – Two RP-SMA RF connectors with automatic antenna diversity switching.
- SiK and multipoint SiK firmware – Field-upgradeable firmware with configurable AT commands.
- Compact and lightweight – Approx. 30 x 57 x 12.8 mm and 14.5 g per modem.
