High-precision DS3231 AT24C32 RTC I2C Clock Module + Battery
Real-time clock module. It allows you to read the time in the form of hours, minutes and seconds and date: month, day, year. The battery used in this module is the popular CR2032 Lithium Cell 3V battery. The module automatically charges the battery. The diode prevents the "reverse" current.
