data-id=\"Description\"\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eUnit RFID2 is a radio frequency identification (RFID) read\/write unit based on the 13.56MHz frequency band. It integrates the WS1850S chip and complies with the ISO\/IEC 14443 Type A\/B standard, supporting data read\/write operations for RFID cards such as MIFARE and NTAG series. The unit communicates via the I2C interface, has a read\/write distance of less than 20mm, and features a LEGO-compatible mounting hole design, making it easy to integrate into creative structures or secure with screws. It is suitable for access control systems, identity authentication, data logging, and other application scenarios that require information verification.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0056\/7689\/2250\/files\/DSC09982.webp?v=1770188058\u0026amp;width=700\" style=\"width: 80%; height: auto;\" alt=\"Unit RFID2\"\u003e\u003c\/p\u003e\n\u003ch2 id=\"features\" data-id=\"Features\"\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCore Chip: WS1850S\u003c\/li\u003e\n\u003cli\u003eOperating Frequency: 13.56 MHz\u003c\/li\u003e\n\u003cli\u003eSupported Standards: ISO\/IEC 14443 Type A\/B\u003c\/li\u003e\n\u003cli\u003eCommunication Interface: I2C\u003c\/li\u003e\n\u003cli\u003eRead\/Write Distance: \u0026lt; 20mm\u003c\/li\u003e\n\u003cli\u003e2 x LEGO-Compatible Mounting Holes\u003c\/li\u003e\n\u003cli\u003eDevelopment Platform\n\u003cul\u003e\n\u003cli\u003eUiFlow1\u003c\/li\u003e\n\u003cli\u003eUiFlow2\u003c\/li\u003e\n\u003cli\u003eArduino IDE\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 id=\"includes\" data-id=\"Includes\"\u003eIncludes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Unit RFID2\u003c\/li\u003e\n\u003cli\u003e1 x HY2.0-4P Grove Cable (20cm)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 id=\"applications\" data-id=\"Applications\"\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSmart home access control system\u003c\/li\u003e\n\u003cli\u003eVehicle management\u003c\/li\u003e\n\u003cli\u003eIntelligent transportation\u003c\/li\u003e\n\u003cli\u003eSmart bookshelf\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0056\/7689\/2250\/files\/6_2f78a9e6-9a36-4c28-8d68-35243da67526.webp?v=1770188099\u0026amp;width=700\" style=\"width: 80%; height: auto;\" alt=\"Unit RFID2\"\u003e\u003c\/p\u003e\n\u003ch2 id=\"specifications\" data-id=\"Specifications\"\u003eSpecifications\u003c\/h2\u003e\n\u003cdiv class=\"table-container\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eRead\/Write IC\u003c\/td\u003e\n\u003ctd\u003eWS1850S\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Freq\u003c\/td\u003e\n\u003ctd\u003e13.56MHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Interface\u003c\/td\u003e\n\u003ctd\u003eI2C @0x28\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupported Prot\u003c\/td\u003e\n\u003ctd\u003eISO\/IEC 14443 Type A\/Type B\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Size\u003c\/td\u003e\n\u003ctd\u003e48.0 x 24.0 x 8.0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Weight\u003c\/td\u003e\n\u003ctd\u003e6.0g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Size\u003c\/td\u003e\n\u003ctd\u003e138.0 x 93.0 x 16.0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGross Weight\u003c\/td\u003e\n\u003ctd\u003e11.3g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0056\/7689\/2250\/files\/1920x2260_66ee25b9-7a53-499b-b582-1d1c6f0d5b8a.webp?v=1770188125\u0026amp;width=700\" style=\"width: 80%; height: auto;\" alt=\"Unit RFID2\"\u003e\n\u003ch2\u003eLearn and Documents\u003c\/h2\u003e\n → DOCUMENTS \n\u003c\/div\u003e","brand":"m5stack-store","offers":[{"title":"Default Title","offer_id":48619342463198,"sku":"oke1787247129308","price":3.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0745\/0705\/9422\/files\/rfid-2-unit-ws1850s_1.jpg?v=1787247137","url":"https:\/\/primewearfashion.shop\/products\/rfid-2-unit-ws1850s","provider":"My Store","version":"1.0","type":"link"}
