DS3231 RTC Clock Module - 2 Pack High Precision Real Time Clock For Arduino

About This Product

Arduino and electronics enthusiasts, this DS3231 RTC module is about to make your projects way more accurate! This isn't your basic clock module - it's temperature-compensated for incredible precision, keeping time within ??5 PPM (that's about ??0.432 seconds per day!). The package includes two modules, so you've got a backup or can use them in different projects. They work with both 3.3V and 5V systems without needing level shifters, which makes integration super easy. The built-in battery backup means your clock keeps ticking even when main power is off - no more resetting the time every time you unplug your project. It handles all the calendar functions including seconds, minutes, hours, date, month, year, and even leap year calculations all the way to 2100. Whether you're building data loggers, weather stations, automated systems, or any project that needs reliable timekeeping, these DS3231 modules deliver professional-grade accuracy without the professional price tag. The I2C interface makes wiring straightforward, and the included temperature sensor adds even more functionality. Seriously, if you've been frustrated with drifting clocks in your electronics projects, this is the solution you've been looking for!
