The RadioMaster XR3 2.4GHz ELRS Receiver packs robust ExpressLRS performance into a tiny footprint, measuring just 20 x 15 mm. Powered by the third-generation Semtech LR1121 transceiver, it handles 2.4 GHz operation with impressive range and sensitivity while keeping weight and size to a minimum. Designed to slot seamlessly into the ExpressLRS ecosystem, the XR3 lets you focus on flying by delivering a reliable, low-latency link even in challenging environments.
A standout in the XR3’s hardware package is the Skyworks RFX2401C, which provides an LNA to boost receiver sensitivity and unlock clearer signal reception. The included PA delivers up to 100 mW of telemetry-capable power, contributing to reliable data transmission alongside control. Antenna switching supports diversity, helping mitigate multipath and weak-signal scenarios by selecting the best available antenna path in real time.
