DS3231 i2C Precision Clock RTC with AT24C32 Memory

DS3231 i2C Precision Clock RTC with AT24C32 MemoryDS3231 Module is a Bread Board friendly extremely precise I2C real time clock Module.

This module made using DS3231 RTC and AT24C32 EEPROM integrated with temperature compensated crystal oscillator.

It also has a built-in comparator which monitors the status of VCC to detect power failures and to automatically switch to backup power supply.

Features:

• Accurate RTC manages all timekeeping functions
• Battery-backup input for continuous timekeeping
• Low power operation extends battery-backup run time
• Breadboard-friendly 6-pin SIP header

Applications:

• Create a clock project using an LCD, OLED or HDMI display
• Time-stamp datalogging projects
• Control events to occur at specific time of day, day of week, etc.
