RFD900ux Long‑Range Radio Modem Module

Product Overview

A compact yet powerful long‑range telemetry modem module designed for reliable wireless data communication in UAVs, RC drones, robotics, and remote monitoring systems. This module supports high throughput, encrypted long-distance transmission, and is compatible with a range of firmware configurations including point-to-point, multipoint, and mesh networking.

Key Features

• Multi‑Mode Firmware Support
  Ready-to-use SiK point-to-point firmware with optional asynchronous and synchronous multipoint firmware for versatile networking setups.

• High Data Rates & Encryption
  Air data rates of up to 500 kbps, plus hardware-accelerated AES encryption ensure efficient and secure transmission.

• Antenna Diversity for Improved Link Stability
  Two u.FL RF connectors with automatic diversity switching to maintain optimal signal reception and transmission.

• Powerful 1 W Transmission
  Up to +30 dBm output power, adjustable in 1 dB increments for fine control over range and regulatory compliance.

• Compact and Lightweight
  Measures approximately 25 × 33 × 10.4 mm and weighs around 10 g, including heatsink and RF shield—ideal for weight-sensitive builds.

• Full Electrical Protection & Filtering
  All I/O pins include ESD protection and filtering, complemented by TX low-pass filtering and high-performance RX front-end components to reduce noise and interference.

• Wide Compatibility & Open Configuration
  Fully compatible with prior-generation RFD900x modems. Configurable via AT commands, supporting UART data rates up to 1 Mbps.

• Long‑Range Capability
  Effective line-of-sight range exceeding 40 km, dependent on antenna and ground station setup.
