• Receiver Sensitivity: -134 dBm
• Supported Firmware: ImpactLRS / MILELRS
• Communication Protocol: CRSF (UART)
• Antenna Connector: IPEX

Power Supply

• JR Input: 7.4 – 12.6 V
• XT30 Input: 12.6 – 26 V (3S – 6S)
• Power Consumption: 36 W
• For Logic Module Power: 5 – 12 V

Advantages and Applications

• Ultra-long-range and stable communication, ideal for extended missions, flights, and industrial tasks where signal reliability over long distances is crucial.
• High receiver sensitivity (-134 dBm) allows maintaining communication in challenging radio interference conditions and when operating in densely built-up areas or over long distances.
• Support for modern ImpactLRS and MILELRS firmware ensures flexible integration with control equipment and opens up possibilities for fine-tuning communication parameters.
• Flexible power options (JR and XT30, compatibility with 3S–6S batteries) allow the module to be used in various drone and ground station configurations.
• The IPEX connector makes antenna connection simple and reliable, while the CRSF (UART) protocol ensures fast telemetry and command data exchange.

The module is part of the Coalas systems 34 series ecosystem and is designed for professional pilots and developers who require the maximum possible range and signal stability. In combination with compatible 34 series receivers, the module creates a reliable communication infrastructure for complex FPV projects and industrial applications.

Coalas systems offers solutions that combine a wide operating frequency range (270–410 MHz), a broad range of output powers (from 50 mW to 12 W), and modern protocols, making this module an ideal choice for tasks with increased demands for range and communication channel stability.
