DS3231 AT24C32 RTC time module - precision clock on I2C
Real-time clock module.
The module allows you to read the time in the form of hour, minute and second and the date: month day, year.
The battery used in this module is the popular CR2032 Lithium Cell 3V battery.
The module charges the battery by itself.
Diode prevents "backflow" of current.
