DS1307 Real Time Clock Module with AT24C32 EEPROM
$4.95
SKU 716537
Keep track of time and date with Arduino and more using the DS1307 Real Time Clock Module with AT24C32 EEPROM from PMD Way.
This small board contains a DS1307 real-time clock IC with an optional CR2032 backup battery. It's one of the easiest to use RTCs out there, with Arduino and other libraries or simply use I2C commands to set and retreive the time and date.
Along with the DS1307 real time clock, the module also has an Atmel 24C32 EEPROM chip which is handy for storing data without worrying about power loss.
