Add this DS3231 Real Time Clock Module on your Raspberry Pi to allow your microcontroller project to keep track of time even when it is reprogrammed, when the main power is lost or your device gets interrupted. This module allows you to have correct timekeeping, even without an internet connection. This is an extremely accurate I2C real-time clock (RTC) based of DS3231 chip which is the best to use in stand-alone projects.
This module has pins aligned to directly plug in to the GPIO headers of the Raspberry Pi or you may also use some wires to have your own connection.
