Real-Time Clock Module for Arduino

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.

• 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 XC-4250 and our Arduino board for a huge clock!
• Ideal for datalogging projects
• Free software library and examples
• Dimensions: 23(W) x 18(H) x 5(D)mm
