DS3231 AT24C32 RTC Clock Module - High Precision Real Time Clock With IIC Interface

About This Product

Electronics hobbyists and makers, this DS3231 real-time clock module is incredibly accurate and feature-packed! The high-precision DS3231M clock chip maintains amazing accuracy - within 2ppm, which translates to about just one minute of error per year. The built-in AT24C32 memory gives you 32K of storage capacity for data logging or configuration settings. What's really useful is the IIC bus interface that works with most microcontrollers, with transmission speeds up to 400KHz at 5V. The module operates between 3.3V and 5.5V, making it compatible with Arduino, Raspberry Pi, and other popular platforms. It includes a temperature sensor with ±3°C accuracy and provides complete calendar functionality with seconds, minutes, hours, day, date, month, and year - including leap year compensation all the way to 2100. You also get programmable square-wave output, two time-of-day alarms, and push-button reset functionality. The package includes a 10-pin male-female cable for easy connection, though you'll need to provide your own CR2032 or LIR2032 battery. Whether you're building data loggers, automated systems, or any project that needs reliable timekeeping, this module delivers professional-grade accuracy in a compact, easy-to-use package that's perfect for both beginners and advanced users.
