Real Time Clock Module (RTC) DS1307

45.00 EGP

The DS1307 RTC Module is a widely used real-time clock module that provides timekeeping functions including seconds, minutes, hours, day, date, month, and year – all via a simple I2C interface. It’s ideal for Arduino, Raspberry Pi, and other microcontroller projects that need accurate time tracking, even when the main system is powered off.

With a backup CR2032 battery (not always included), the DS1307 continues keeping time in the absence of external power, making it perfect for data logging, alarms, and timed automation.
