Introducing the XR4 XrossBand Receiver - The Pinnacle of compact Dual-Band Performance

The XR4 Receiver is a cutting-edge true diversity dual-band receiver featuring dual LR1121 RF transceivers, designed to leverage the advanced ExpressLRS Gemini Xrossband protocol (Gem-X). It seamlessly supports both the 2.4GHz and Sub-G 900MHz bands, and its dual T-type antennas provide superior reception sensitivity and connection stability for optimal performance.

Built with two independent RF circuits, the XR4 offers versatile operation modes, allowing you to switch between Gemini
single-frequency or Xrossband dual-band modes, and can be tailored to your specific needs. The integrated Wi-Fi module simplifies firmware updates and configuration via a user-friendly WebUI on your PC or mobile device.

With ultra-low latency and a high refresh rate, the XR4 excels in delivering a stable, rock-solid RF link, even in demanding
long-range or challenging environments. Its compact, lightweight design is perfect for drones, and fixed-wing models, offering reliable connectivity in critical situations where every signal matters. The XR4 ensures you maintain the most secure and robust RF link available, providing unbeatable reliability in the most demanding conditions
