Description

The R9M Lite Pro module represents an upgraded, high-performance 900MHz system for FrSky’s ACCESS ecosystem. Its high-speed digital interface ensures low-latency communication, while the robust CNC aluminum construction manages thermal loads during sustained high-power transmission. The module is engineered for reliability in long-range FPV, drone racing, and autonomous UAV applications where signal integrity is critical.

Operating on the 868MHz (EU) or 915MHz (non-EU) bands, it provides a robust link less susceptible to 2.4GHz congestion. The module supports a wide range of RF power settings, from a low 10mW for close-range flying to a maximum of 1W for extreme distance operations, with telemetry functionality maintained across all power levels.

Key Features

  • Long-range 868/915MHz frequency band with reduced interference compared to 2.4GHz systems.
  • Four selectable RF power outputs: 10mW, 100mW, 500mW, and 100mW-1W (adjustable).
  • High-speed digital module interface for low-latency control and telemetry.
  • Built-in spectrum analyzer visualizes RF environment for optimal channel selection.
  • CNC-machined aluminum protective shell ensures durability and enhances heat dissipation.
  • Full compatibility with FrSky ACCESS protocol and receivers (R9 & TD series).
  • Antenna detection and SWR (Standing Wave Ratio) indicator for monitoring antenna health.
  • Supports 16 channels for precise control and complex model configuration.

Applications

  • Long-range FPV drone builds requiring reliable control links beyond 2.4GHz range.
  • ACCESS protocol-based radio systems for competitive drone racing and freestyle.
  • Heavy-lift cinematography or mapping drones where control signal penetration is crucial.
  • DIY UAV and robotics projects needing a robust, telemetry-enabled 900MHz control system.
  • Upgrading compatible FrSky transmitters for extended range and advanced RF analysis.

Frequently Asked Questions

What FrSky transmitters is the R9M Lite Pro module compatible with?

The R9M Lite Pro module is designed for FrSky radios running the ACCESS protocol. It is perfectly compatible with models like the Taranis X-Lite PRO and X9 Lite. It will also work with other FrSky transmitters that have a compatible module bay and support the ACCESS firmware.

What is the maximum RF power output of the R9M Lite Pro?

In non-LBT regions, the R9M Lite Pro supports adjustable RF power up to 1 Watt (1000mW). It offers several preset levels including 10mW, 100mW, 500mW, and a variable high-power mode ranging from 100mW to 1W. Always ensure your selected power level complies with local radio transmission regulations.

Does the R9M Lite Pro support telemetry, and how does RF power affect it?

Yes, it fully supports bidirectional telemetry data transmission. The module offers different power modes: a Telemetry mode at 25mW (for LBT regions) and higher-power Non-Telemetry modes (200mW, 500mW). Telemetry is maintained in the designated mode, but range and update rate may vary with power setting and environmental conditions.

What is the purpose of the integrated spectrum analyzer?

The built-in spectrum analyzer allows pilots to visually scan the 868/915MHz band directly on their transmitter's screen. This function helps identify clear channels with minimal interference, which is critical for optimizing signal reliability and reducing packet loss during long-range or crowded multi-pilot FPV sessions.
