[Pre-order] XR2 Nano 2.4GHz ExpressLRS Receiver

The XR2 Receiver is a nano-sized powerhouse engineered for 2.4GHz ExpressLRS, featuring an integrated tower antenna that delivers exceptional reception within its ultra-compact design. With a footprint of just 16x12mm and a lightweight of only 0.8g, it fits seamlessly into even the most space-constrained builds. Driven by the advanced Semtech LR1121 transceiver (third generation), the XR2 offers compatibility with all ELRS 2.4GHz transmitters and unlocks the benefits of DK500Hz mode for LR1121-based systems, ensuring unparalleled reliability and responsiveness. The built-in Wi-Fi module simplifies firmware updates and configuration via a WebUI on your PC or mobile device. With ultra-low latency and high refresh rates, the XR2 stands out in Whoops, micro drones, and fixed-wing models, where every gram and millimeter counts for peak performance.
