DS1307 Real Time Clock RTC Module

Overview of this DS1307 Real Time Clock RTC Module

Introducing DS1307 Real Time Clock RTC Module at best price in India. This DS1307 RTC module keeps track of the current time and date, including seconds, minutes, hours, day, date, month, and year even when your main microcontroller is powered off. It comes with a built-in battery holder for a coin cell (usually CR2032) and so it can keep the time running for years even if the main power supply is disconnected.

This module uses the I2C communication protocol and which means it only needs two wires (SCL and SDA) to connect with microcontrollers like Arduino, Raspberry Pi, ESP8266, etc. It’s mostly used in electronics projects and supports various platforms, making it ideal for hobbyists, students, and engineers alike.

Features

Keeps Accurate Time – It tracks seconds, minutes, hours, day, date, month, and year accurately.

Built-in Battery Backup – It has a coin cell battery slot to keep time running even when the power is off.

Uses I2C Communication – Module communicates easily with microcontrollers like Arduino using just two wires (SCL and SDA).

Low Power Consumption – Uses very little power, so the battery lasts a long time.

Supports Leap Years – Automatically adjusts the date during leap years up to the year 2100.

Compact Size Module – Small and easy to fit in embedded or DIY projects.
