RadioMaster XR2 Nano 2.4GHz ExpressLRS Receiver

The XR2 Receiver is a nano-sized ExpressLRS powerhouse designed specifically for 2.4 GHz performance in the smallest possible footprint. With an ultra-compact 16 × 12 mm form factor and weighing only 0.8 g, the XR2 is purpose-built for space- and weight-critical applications such as whoops, micro drones, and compact fixed-wing aircraft.

At its core, the XR2 is powered by the third-generation Semtech LR1121 transceiver, delivering outstanding sensitivity, link stability, and full compatibility with all ExpressLRS 2.4 GHz transmitters. Support for DK500Hz mode unlocks ultra-low latency and high refresh rates on LR1121-based systems, ensuring fast, precise control and rock-solid reliability.

The integrated 2.4 GHz tower antenna provides excellent reception without the need for external antennas, simplifying installation and improving durability in tight builds. Firmware updates and configuration are effortless thanks to the built-in Wi-Fi, allowing access to the ExpressLRS WebUI directly from your PC or mobile device—no extra hardware required.

Designed with both performance and ease of use in mind, the XR2 delivers cutting-edge ExpressLRS capability in a truly nano package.
