These are a lower cost alternative to the RP2 ELRS receivers, arying much of the same capability (and a few differences).\u003c\/p\u003e\n\u003cp\u003eThe main differences are this one is SLIGHTLY bigger than the RP2, so please check fit in any custom design. And they have a boot button in place of the boot pad of the RP2. As well as addition of a second TX\/RX pad pair, allowing for additional functionality, or with reconfiguration, up to 4 PWM channels! (with some fine soldering, as the pads are quite small).\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cp\u003e\u003cspan\u003eThe XR2 Receiver is a tiny but powerful device designed for 2.4GHz ExpressLRS, featuring an integrated tower antenna that provides excellent reception in its small size. Measuring just 16x12mm and weighing only 0.8g, it easily fits into even the tightest spaces in your build. Powered by the advanced third-generation Semtech LR1121 transceiver, the XR2 is compatible with all ELRS 2.4GHz transmitters and supports DK500Hz mode for LR1121-based systems, ensuring high reliability and quick response. Its built-in Wi-Fi module makes firmware updates and setup simple through a WebUI on your PC or mobile device. With ultra-low latency and high refresh rates, the XR2 is perfect for any project where small size, speed, and accuracy are key.\u003cbr\u003e\u003cbr\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0651\/4383\/2807\/files\/01_b8869e3d-927d-4d19-9336-a89a96b9306c.jpg?v=1777168347\" alt=\"\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eIntegrated 2.4GHz tower antenna\u003c\/li\u003e\n\u003cli\u003eExpressLRS 2.4GHz\u003c\/li\u003e\n\u003cli\u003eESP32C3 high-performance MCU\u003c\/li\u003e\n\u003cli\u003eSemtech LR1121 Transceiver\u003c\/li\u003e\n\u003cli\u003eSecondary UART port for advanced functionality\u003c\/li\u003e\n\u003cli\u003eCastled pads for easy soldering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eItem: XR2 Nano 2.4GHz ExpressLRS Receiver\u003c\/li\u003e\n\u003cli\u003eType: ISM2.4\u003c\/li\u003e\n\u003cli\u003eMCU: ESP32C3\u003c\/li\u003e\n\u003cli\u003eRF Chip: Semtech LR1121\u003c\/li\u003e\n\u003cli\u003eAntenna: Integrated 2.4GHz Tower Antenna\u003c\/li\u003e\n\u003cli\u003eFrequency Range: 2.400 - 2.479GHz\u003c\/li\u003e\n\u003cli\u003eTelemetry Power: 10mW\u003c\/li\u003e\n\u003cli\u003eMaximum Packet rate: DK500Hz\u003c\/li\u003e\n\u003cli\u003eMinimum Packet refresh rate: 50Hz\u003c\/li\u003e\n\u003cli\u003eWorking voltage: 5V\u003c\/li\u003e\n\u003cli\u003eWeight: 0.8g\u003c\/li\u003e\n\u003cli\u003eDimension: 16mm * 12mm * 6mm\u003c\/li\u003e\n\u003cli\u003eFirmware Version: ExpressLRS v3.5.1 pre-installed\u003c\/li\u003e\n\u003cli\u003eFW Target:  RadioMaster XR2 2.4 RX\u003c\/li\u003e\n\u003cli\u003eBus interface 1: CRSF\u003c\/li\u003e\n\u003cli\u003eBus interface 2: UART\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0651\/4383\/2807\/files\/02_4c0b9bb1-ea35-4341-ba39-766c1e866940.jpg?v=1777168351\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0651\/4383\/2807\/files\/03_9e0b7f49-f300-4c40-b413-b0ab106ced73.jpg?v=1777168356\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0651\/4383\/2807\/files\/04_14aceae2-7d33-4151-916e-6b68ed7f8d5c.jpg?v=1777168363\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0651\/4383\/2807\/files\/11_bd58cfc9-d3bf-4369-9778-1b7b04d5700c.jpg?v=1777168366\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0651\/4383\/2807\/files\/08_c0b879ca-18d5-4bf7-a14c-a5c1e42d331d.jpg?v=1777168373\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0651\/4383\/2807\/files\/09_480x480_2c827c40-4e0e-4a8c-a1aa-de4a78862a00.jpg?v=1777168378\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0651\/4383\/2807\/files\/10_70804514-a950-4465-ba17-7309a5d04863.jpg?v=1777168382\" alt=\"\"\u003e\u003c\/p\u003e\n\u003c\/div\u003e","brand":"RadioMaster RC","offers":[{"title":"Default Title","offer_id":52008814772455,"sku":"RX-RM-XR2-ELRS","price":25.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0651\/4383\/2807\/files\/1_1800x1800_c4025cac-04a5-401e-87dd-a4cd2cd8b6df.png?v=1777168343","url":"https:\/\/combatrobotics.co.nz\/products\/radiomaster-xr2-expresslrs-elrs-2-4ghz-nano-receiver","provider":"Combat Robotics NZ","version":"1.0","type":"link"}
