Introduction

This is a highly accurate Real-Time Clock (RTC) that plugs directly into the Raspberry Pi and includes a battery backup. Unlike other RTCs available， this module is installed directly into the GPIO header pins with no wiring or soldering.

Features

• Very accurate timekeeping
• Directly plugged into the GPIO header pins
• Compact with no wiring or soldering required
• Fits inside most cases easily

Why a Real-Time Clock is required?

The Raspberry Pi is an ultra-small and ultra-low cost computer. In order to achieve this size and price， several non-essential items usually found on a computer had to be omitted. Laptops and computers keep time when the power is off by using a pre-installed， battery powered Real-Time Clock (RTC). However， the Real-Time Clock module is not included with the Raspberry Pi. To keep time， the Raspberry Pi updates the date and time automatically over the internet via Ethernet or WiFi. The Raspberry Pi will simply revert back to the standard date and time settings when the network connection is removed. So， for projects which have no internet connection， you may want to add a battery powered RTC to help your Pi keep time!
