Also, it has automatic compensation for leap-years and months with fewer than 31 days.Īs the module works with 3.3V as well as 5V input it becomes compatible with most of the development boards available in the market. It can also store the day of the week, date, month, and year. It can store and maintain, Time including Hours, Minutes, and Seconds. For starters, it is very low cost and anyone looking for cheap RTC Modules may go for it. But, DS3231 comes with a CR2032 3V lithium cell through which it keeps the time on track without power too.ĭS3231 Module comes with a load of features. You may ask, what is the need of an external module for managing time when Arduino itself has a clock built-in ? Well, the clock inside Arduino resets every time you upload a new code or disconnect the power. It is highly accurate and can precisely store “Hours, Minutes and Seconds along with Day, Date, Month and year”
