Description:
The DS1302 based Real-Time Clock Module can be used with Arduino or any other micro-controllers for timekeeping. The DS1302 is designed to operate on very low power and retain data and clock information on less than 1uW. It communicates with a microprocessor via a simple serial interface.
The real-time clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year.
The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator.
**Battery NOT Included**
