DS1302 Real Time Clock (RTC) Module

Overview of this DS1302 Real Time Clock Module

Introducing Roboway DS1302 Real Time Clock (RTC) Module  at best price in India. This module keeps track of time even when your main device is off or restarted. It works with a small coin-cell battery and so it remembers time even without power. This module can tracks date and time and stores seconds, minutes, hours, day, date, month, and year, including leap years.

This module comes with 31 bytes of SRAM memory for small data storage. It is communicates with microcontrollers (like Arduino) using a simple 3-wire interface and Designed to use very little electricity, perfect for long-term use. It comes in green color.
