Radiomaster Nomad Gemini Xrossband ExpressLRS 2.4GHz/900MHz Dual 1W Transmitter Module

The RadioMaster Nomad Gemini Xrossband ExpressLRS Dual 1W Transmitter Module enables simultaneous operation in two frequency bands thanks to Gemini Xrossband technology. The use of two Semtech LR1121 transceivers allows for efficient signal transmission at 2.4GHz and 900MHz with minimal latency. Built-in ESP32 and ESP32c3 microcontrollers optimize performance and expand functionality. A signal refresh rate of up to 500Hz (with the prospect of expansion to 1000Hz) improves control sensitivity. Wi-Fi and Bluetooth support simplifies setup and firmware updates. The system is compatible with all ExpressLRS receivers in the 2.4GHz and 900MHz bands.
