DS3231 Real Time Clock Module

The DS3231 Real Time Clock (RTC) Module is a compact electronic device used for accurate timekeeping in various applications. It utilizes a highly precise quartz crystal oscillator and provides real-time information on date, time, and day of the week. It can be interfaced with microcontrollers via the I2C bus and use CR2032 coin cell battery for backup power
