Radiomaster XR2 Nano is a small receiver with a ceramic 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 XR2 uses a Semtech LR1121 chip, enabling operation on 2.4GHz and 868/915MHz frequencies. However, due to the fixed ceramic antenna, only the 2.4GHz band can be used. Thanks to its compact size, low weight, and affordable price, this receiver is ideal for racing drones or smaller freestyle drones. The receiver also features a second set of UART pads for potential future expansion.
