HiLetgo 5pcs DS3231 AT24C32 Clock Module Real Time Clock Module IIC RTC Module for Arduino Without Battery

hello then dogs here from how to catch onyx calm in this Arduino tutorial we will learn how to use the ds3231 real-time clock module the first question that comes here is why we actually need a separate real-time clock for our arduino project when the arduino itself has a built-in timekeeper well the point is that the real time clock module runs on a battery and can keep track of the time even if we reprogram the microcontroller or disconnect the main power the ds3231 is a low-cost highly accurate real-time clock which can maintain hours minutes and seconds as well as they mount any R information also it has automatic compensation for leap years and four months with fewer than 31 days the module can work on either 3.3 or 5 volts which makes it suitable for many development platforms or microcontrollers the battery input is 3 volts and typical cr2032 3 volts battery can power the module
