## Description

This handy module keeps accurate time for years using a tiny coin-cell, and is very simple to connect to your Arduino project.

A driver library allows your program to easily set or read the time and date. Perfect for clock projects, dataloggers or anything that needs to know the date and time. Features Set or read accurate time and dates from your Arduino.

Keeps time without power using a CR1632 coin cell battery backup (supplied) & 236 Bytes of addressable non-volatile memory, save serial numbers and important values. Add a Dot Matrix Display panel and one of our Arduino-compatible boards for a huge clock!

Ideal for data logging projects.
