{"product_id":"real-time-clock-module-ds1307","title":"Real Time Clock Module - DS1307","description":"\u003cp class=\"isSelectedEnd\"\u003eThe Real Time Clock Module - DS1307 is a low-power real-time clock module designed to accurately maintain time and calendar information even when the main power supply is turned off. Built around the popular DS1307 RTC IC, the module keeps track of seconds, minutes, hours, day, date, month, and year, including automatic leap-year compensation. It is widely used in Arduino projects, Raspberry Pi applications, ESP32 development, data logging systems, clocks, timers, home automation, IoT devices, and embedded systems where accurate timekeeping is required.\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003eThe module communicates with microcontrollers through the industry-standard I²C (Two-Wire) interface, requiring only two communication pins for operation. It includes a backup battery holder for a CR2032 coin cell, allowing the RTC to continue keeping accurate time even during power interruptions. The module also features an onboard 32.768kHz crystal oscillator that provides stable clock generation for reliable long-term operation.\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003eIn addition to real-time clock functionality, many DS1307 modules include a 24C32 I²C EEPROM that provides 32Kb (4KB) of non-volatile memory for storing configuration settings, calibration data, user parameters, or small amounts of application data. The module is fully compatible with popular development platforms including Arduino UNO, Nano, Mega, ESP32, ESP8266, STM32, Raspberry Pi, PIC, AVR, and other I²C-enabled microcontrollers.\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003eDesigned for ease of integration, the DS1307 RTC Module operates from a 5V supply and provides a simple interface for adding accurate timekeeping capabilities to electronic projects. Its compact size, low power consumption, backup battery support, and wide software compatibility make it an ideal solution for students, hobbyists, engineers, educators, and embedded system developers.\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eKey Features\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul data-spread=\"false\"\u003e\n\u003cli\u003e\u003cspan\u003eBased on the DS1307 Real Time Clock IC\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eMaintains accurate time and calendar information\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eTracks seconds, minutes, hours, day, date, month, and year\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eAutomatic leap-year compensation\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eStandard I²C (Two-Wire) communication interface\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eOperates from a 5V power supply\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eBackup battery support using CR2032 coin cell\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eContinues timekeeping during power loss\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eOnboard 32.768kHz crystal oscillator\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eLow power consumption\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eCommonly includes onboard 24C32 I²C EEPROM\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eNon-volatile memory for user data storage\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSimple four-pin interface\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eEasy integration with microcontrollers\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eCompatible with Arduino, ESP32, ESP8266, STM32, Raspberry Pi, PIC, and AVR\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eIdeal for clocks and calendar applications\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSuitable for data logging systems\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003ePerfect for IoT and automation projects\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eReliable long-term timekeeping\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eCompact PCB design\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eBreadboard friendly\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSuitable for students, hobbyists, and professional developers\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Roboracter","offers":[{"title":"Default Title","offer_id":46867708477494,"sku":"QJ74WTN5OL","price":60.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0715\/0731\/2694\/files\/DS1307_Real_Time_Clock_Module-2.png?v=1783947555","url":"https:\/\/roboracter.in\/products\/real-time-clock-module-ds1307","provider":"Roboracter","version":"1.0","type":"link"}
