DS1307 Real Time Clock Module

DFR0151 Real Time Clock Module DS1307


This module comes fully assembled and pre-programmed with the current time. The included Lithium coin cell battery (CR1225 41mAh) will run the module for a minimum of 9 years (17 years typical) without external 5V power. The DS1307 is accessed via the I²C protocol. Except the DS1307 real time clock, the module also integrates the I²C EEPROM chip (24C32) and the DS18B20 sensor interface. The I²C EEPROM makes it possible to save the sensor data easily without spending too much microcontroller source. And the DS18B20 interface with the pull-up resistor embedded will be helpful to extend temperature monitoring feature for your project.
