DS1307 RTC Real Time Clock Module for ARDUINO

Fully assembled real time clock and calendar module with additional memory on DS1307 chip for Arduino.

The DS1307 real time clock module is used in layouts and projects on microcontrollers to obtain information about the real current date and time.
To use the module, you must first assemble a layout using it, create a control program and start working.

The real-time module is controlled by Arduino controllers or other control microprocessor devices using the I2C interface.

The DS1307 chip has a programmable square wave generator on board, which allows you to generate one of four frequencies (1Hz, 4096Hz, 8192Hz or 32768Hz), which in turn can be used to correct the error of the quartz resonator.

The DS1307 real-time clock module has two terminal blocks - P1 and P2, as well as a slot for installing
CR2032 batteries.

Block P1 has contacts SQ, DS, SCL, SDA, VCC, GND, BAT
Block P2 has contacts DS, SCL, SDA, VCC, GND
The module is powered from the Arduino controller, another microprocessor control device, or from an external power source.

The DS1307 chip has a built-in block that detects an emergency power off and automatically connects a backup battery. At the same time, the countdown continues and after the restoration of power, the clock shows the correct time.
