RadioMaster Nomad Dual 1-watt Gemini Xrossband ExpressLRS Module

RadioMaster Nomad Dual 1-watt Gemini Xrossband ExpressLRS Module is an advanced dual-band radio transmitter designed for FPV drone transmitters, airplanes, fixed-wing builds, and long-range RC platforms where maximum link reliability, interference resistance, and extreme range are essential.

Unlike standard single-band units, this module supports evolutionary Gemini Xrossband technology, enabling simultaneous packet transmission across both 2.4GHz and 915/868MHz bands. This provides superior link stability, instantaneous failover, and robust multi-path interference mitigation. If conditions degrade on one frequency, the secondary band maintains an uninterrupted control path.

Equipped with dual independent Semtech LR1121 RF chips and dual power amplifiers delivering up to 2 × 1000 mW (2 × 1W) of output power, the Nomad ensures exceptional link performance. An advanced thermal management system with an integrated heatsink prevents thermal throttling during heavy use.

Operating within a 6–16.8V power input range (via XT30), it is fully compatible with cutting-edge dual-band receivers (Gem-X) as well as legacy single-band 2.4GHz or 900MHz ELRS receivers. It ships with adapters for both Micro and Nano transmitter bays.

With built-in Wi-Fi and Bluetooth support, configuring parameters and flashing firmware is seamlessly handled via the standard ExpressLRS web interface.
