Key Features of DS1307 Real Time Clock Module

Battery-backed timekeeping: Maintains accurate date and time even when main power is disconnected, thanks to the onboard CR2032 coin cell.
Simple I2C interface: Only two data lines (SDA, SCL) needed - saves precious GPIO pins and simplifies wiring.
Plug-and-play with Arduino: Extensive library support (RTClib, DS1307RTC) means you can read time in just a few lines of code.
56 bytes of NV SRAM: Store small amounts of user data (settings, calibration values) that persist through power cycles.
Programmable square wave output: Use the SQW pin for precise timing interrupts or as a clock source for other circuits.
Compact and breadboard-friendly: Standard 2.54 mm header pins fit directly into breadboards and prototyping setups.
