TheRadioMaster Nomad Gemini Xrossband ExpressLRS Dual 1W transmitter module provides simultaneous operation in two frequency bands thanks to Gemini Xrossband technology. The use of two Semtech LR1121 transceivers allows efficient signal transmission at 2.4GHz and 900MHz with minimal delay. The built-in ESP32 and ESP32c3 microcontrollers optimize performance and expand functionality. The signal refresh rate of up to500Hz (expandable to 1000Hz) improves control sensitivity. Wi-Fi and Bluetooth support simplifies configuration and firmware updates. The system is compatible with all ExpressLRS receivers in the 2.4GHz and 900MHz bands.
