Description

The Radiomaster XR4 receiver supports 2.4GHz and Sub-G 900MHz bands using the ExpressLRS Gemini Xrossband (Gem-X) protocol. Equipped with two independent LR1121 transceivers, it provides stable communication thanks to true spread spectrum reception. Two operating modes allow it to be used in single-frequency or dual-band mode, depending on your needs. The integrated Wi-Fi module simplifies firmware updates and configuration via the WebUI. The receiver has a low latency and high refresh rate, which improves the drone's controllability. Dual T-shaped antennas provide high reception sensitivity and signal reliability. An additional UART port expands connectivity and integration options.
