Tiny RTC - DS1307 Time Module - Real Time Clock - I2C - Arduino

A module with a real-time clock and its own battery power supply. It allows you to read the time in the form of hours, minutes and seconds and date: month, day, year. Specification: Module with DS1307 real-time clock and backup battery power supply. It allows you to read the time in the form of hours, minutes and seconds and date: month, day, year. The communication interface is the I2C bus (SDA and SCL lines) The data refresh rate is 1 Hz (1 second). The battery attached to the module allows the system to be operated for up to 9 years without external power supply. Data available: Time: hour (AM, PM), minute, second Date: month, day, year An accurate calendar until 2100 The module has goldpin headers, enabling connection with any development kit. LED signaling Application for breadboards, Arduino etc. Module parameters Real time clock module RTC DS1307 Connected to serial 24C32 memory Built-in 32.768kHz quartz Chip DS1307,24C32 5V power supply built-in basket on (CR2032) - battery not included Current consumption: less than 500 nA Communication interface: I2C / TWI (SDA, SCL) Refresh rate: 1 Hz (1 second) Publicly accessible internal memory: 56 bytes Dimensions: 28 x 28 mm Pinout The 5 V supply voltage is connected to the pin marked with the same symbol. The I2C bus should be connected to the pins SCL - clock line SDA - data line. The SQW pin is the square wave output with the selected frequency GND is the mass of the system.
