Radiomaster XR1 Nano ELRS 868MHz/2,4GHz

Radiomaster XR1 Nano is a small receiver with a single antenna for the ExpressLRS (ELRS) system. ExpressLRS is an advanced open-source RC system with long range, low latency, high refresh rate, and many useful features. Learn more about ELRS here.

The Radiomaster XR1 uses a Semtech LR1121 chip, enabling operation on both 2.4GHz and 868/915MHz frequencies. Due to its single antenna, the receiver cannot receive on both frequencies simultaneously, but the frequency can be easily changed as needed. The 2.4GHz band is ideal for racing and freestyle, offering a fast refresh rate with minimal latency. The 868MHz band, on the other hand, excels in its long-range capabilities. The receiver also includes a second set of UART pads for potential future expansion. Additionally, the telemetry power can reach up to 100mW.

The variants differ only in the supplied antenna.
