RadioMaster Ranger 2.4GHz ELRS TX Module

The RadioMaster Ranger is a high-performance 2.4GHz ExpressLRS module designed for standard JR-bay transmitters like the TX16S and Boxer. Built for pilots demanding ultra-low latency or pushing long-range FPV boundaries, it delivers up to 1W of RF output power housed in a rugged CNC-machined aluminium enclosure that ensures thermal stability during extended flights.

Key features

• Up to 1W (30dBm) maximum output power for deep penetration and long-range reliability.

• CNC-machined aluminium casing with a built-in active cooling system for efficient heat dissipation.

• Integrated OLED display and directional navigation keys for independent parameter adjustments without diving into transmitter LUA scripts.

• XT30 auxiliary power port allows the module to be driven by an external 2S–4S LiPo, preserving your radio's internal battery at high power levels.

• Built-in Wi-Fi and Bluetooth support for wireless ELRS firmware flashing and telemetry forwarding.
