EASY plug Ultimate Starter Learning Kit Project 21: What time is it?

Overview
In this project, we will show you how to display the time and date.
Component Required

• EASY plug control board*1
• EASY plug DS3231 Clock Module*1
• RJ11 cable*1
• USB cable*1

Component Introduction

The DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal.
A real-time clock (RTC) is a computer clock (most often in the form of an integrated circuit) that keeps track of the current time.
It integrated with a battery input, which can maintain accurate timekeeping when power off. The integrated crystal resonator ensures the accuracy of clock. So this RTC solution should be worth to try.

• Temperature range: -40℃ to +85℃
• Timing accuracy: about ± 5ppm
• Output: 1Hz and 32.768kHz
• High speed (400kHz), I2C serial bus
• Supply voltage: 3.3V to 5.5V
• Output Level: TTL level
