{"product_id":"radiomaster-xr2-nano-2-4ghz-expresslrs-receiver","title":"Radiomaster XR2 Nano 2.4GHz ExpressLRS Receiver","description":"\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eFor more details and support, visit \u003ca href=\"https:\/\/www.expresslrs.org\/\" target=\"_blank\" rel=\"noopener\"\u003eexpresslrs.org.\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eFeatures\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eIntegrated 2.4GHz tower antenna\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eExpressLRS 2.4GHz\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eESP32C3 high-performance MCU\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSemtech LR1121 Transceiver\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSecondary UART port for advanced functionality\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCastled pads for easy soldering\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eSpecification\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eItem: XR2 Nano 2.4GHz ExpressLRS Receiver\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eType: ISM2.4\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eMCU: ESP32C3\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eRF Chip: Semtech LR1121\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eAntenna: Integrated 2.4GHz Tower Antenna\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eFrequency Range: 2.400 -
