DS3231 Precision RTC Real Time Clock with Build-in 32K EEPROM

Please note that this module is designed for use with the LIR2032 rechargeable lithium-ion coin cell battery. If you intend to use a CR2032 battery instead, you will need to remove either the resistor or the diode to disable the charging circuit.

Introducing the magnificent Lonely Binary DS3231, the ultimate timekeeping marvel that will never let you miss a beat! Designed with the future in mind, this device is equipped with a battery input terminal, ensuring precise timing even when the main power supply takes a breather. Say goodbye to those frustrating moments of resetting clocks and watches after a power outage!

But that's not all - our DS3231 boasts an integrated crystal oscillator that not only enhances accuracy but also simplifies your production line by reducing the number of components. With options for commercial grade and industrial grade temperature ranges, this 16-pin 300mil SO packaged wonder is built to withstand any environment.

Prepare to be wowed as this remarkable Real-Time Clock (RTC) saves and safeguards every second, minute, hour, day of the week, date, month, and year information. Worried about months with less than 31 days? Fear not! The DS3231 automatically adjusts the date at the end of the month, even accounting for those leap years. We've got your back until the year 2100!

Versatility is our middle name! Choose between the classic 24-hour format or the AM/PM-indicated 12-hour format, whichever suits your style. Plus, we've included not one, but two configurable calendar alarms to keep you on track. Need a little extra rhythm in your life? Our DS3231 also provides a configurable square wave output, because who doesn't love a good beat?

And let's not forget the seamless connectivity! With the I2C bidirectional bus and lightning-fast transmission speed of 400KHz (when working voltage is 5V), accessing the DS3231's treasure trove of data is a breeze.

Embrace the future of timekeeping with the Lonely Binary DS3231 and experience precision, reliability, and a touch of magic. Trust the brand that's committed to keeping you in sync, and let Lonely Binary be your guide through the enchanting world of time.
