The built-in timer can handle some simple timing tasks, but if we want to implement data timestamp recording, clock, alarm clock and other time-span functions, a system power-independent clock RTC is the best choice.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSupport second\/minute\/hour\/day\/month\/year. time data reading and writing\u003c\/li\u003e\n\u003cli\u003e32.768kHz high-precision clock crystal, greatly reducing the time error\u003c\/li\u003e\n\u003cli\u003eLow power consumption, coin battery can work continuously for years\u003c\/li\u003e\n\u003cli\u003eWith century mark\u003c\/li\u003e\n\u003cli\u003eI2C communication interface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eIncludes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x Unit RTC\u003c\/li\u003e\n\u003cli\u003e1x Coin cell battery (38mAh)\u003c\/li\u003e\n\u003cli\u003e1x HY2.0-4P cable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecifications\u003c\/th\u003e\n\u003cth\u003eParameters\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClock chip\u003c\/td\u003e\n\u003ctd\u003eHYM8563\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCrystal Frequency\u003c\/td\u003e\n\u003ctd\u003e32.768kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication interface\u003c\/td\u003e\n\u003ctd\u003eI2C, addr: 0x51, bus max speed 400Kbps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower supply voltage\u003c\/td\u003e\n\u003ctd\u003e5V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNet weight\u003c\/td\u003e\n\u003ctd\u003e4.1g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGross Weight\u003c\/td\u003e\n\u003ctd\u003e8.3g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Dimensions\u003c\/td\u003e\n\u003ctd\u003e48 x 24 x 8mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Size\u003c\/td\u003e\n\u003ctd\u003e67 x 53 x 12mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eDocuments\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/files\/rtc_sch_01.webp?v=1634810551\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/files\/HYM8563_Datasheet_V2.2_cn.pdf?v=1634810551\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eDatasheet\u003c\/a\u003e (HYM8563)\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/github.com\/m5stack\/M5_BM8563\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eExample\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M5Stack","offers":[{"title":"Default Title","offer_id":39496003420243,"sku":"U126","price":4.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/1_1200x1200_2c1bae2e-cb58-41b8-b6ad-2913e26043a2.jpg?v=1634810892","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/real-time-clock-rtc-unit-hym8563","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
