Ideal for electronics hobbyists, DIY enthusiasts, IoT developers, and small manufacturers, this module provides reliable timekeeping for a wide range of projects.\u003c\/p\u003e\n\u003cp\u003eIt includes an onboard battery backup (CR2032 NOT INCLUDED) and maintains accurate timekeeping even when power to the module is interrupted. The RTC tracks seconds, minutes, hours, day, date, month, and year information. The date at the end of the month is automatically adjusted for months with fewer than 31 days, including correction for leap years. The clock operates in either the 24-hour or 12-hour format with an AM\/PM indicator. Two programmable time-of-day alarms and a programmable square-wave output are provided for flexible control.\u003c\/p\u003e\n\u003cp\u003eAddress and data are transferred serially through an I2C bidirectional bus. A precision temperature-compensated voltage reference and comparator circuit monitors the status of VCC to detect power failures, to provide a reset output, and to automatically switch to the backup supply when necessary. The AT24C32 provides 32K of EEPROM storage for your project's data logging or configuration needs.\u003c\/p\u003e\n\u003chr class=\"my-7 border-neutral-300 dark:border-neutral-700\"\u003e\n\u003ch3\u003eDS3231 Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccurate \u0026amp; Reliable Timekeeping:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eDS3231 RTC module maintains precise seconds, minutes, hours, day, date, month, and year, ensuring your projects stay on schedule.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUninterrupted Operation with Battery Backup:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eOnboard battery holder (CR2032 NOT INCLUDED) provides continuous timekeeping even during power outages, preventing data loss.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic Leap Year Correction:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eForget manual adjustments!
