DS3231 i2C Precision Clock RTC with AT24C32 Memory

DS3231 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. AT24C32 provides 32,768 bits of serial EEPROM organized as 4096 words of 8 bits each. This gives you 32Kb of non-volatile memory for your projects. This module can be easily interfaced with Arduino Boards, Raspberry Pi and all Microcontrollers.

The DS3231 AT24C32 Real Time Clock Module adds timestamp and event scheduling information to your microcontroller projects. This module generates seconds, minutes, hours, day, date, month and year, and provides timekeeping until 2100 while compensating for leap years.

DS3231 AT24C32 Real Time Clock Module 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

DS3231 AT24C32 Real Time Clock Module 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.
