Popis produktu

The real time clock module provides seconds, minutes, hours, days, date, months, and year information. The end of the month date is automatically adjusted for months with less than 31 days, including correction for leap years. This real time clock module communicates with a microprocessor via a simply serial interface. The clock module operates in either 24-hour or 12-hour format with AM / PM indicator.
