Raspberry Pi RTC High Precision Clock Module DS3231

Raspberry Pi RTC High Precision Clock Module DS3231

Mini Real-Time Clock module, designed for Raspberry Pi but can also be used with Arduino. It plugs into the Raspberry Pi GPIO interface and requires no additional connections.

The board has a battery input that maintains accurate timekeeping when the main power of the device is cut off. The RTC holds information for seconds, minutes, hours, days, dates, months, and years. The date at the end of the month is automatically adjusted for months with less than 31 days, including leap year corrections. The clock operates in either 24-hour or 12-hour format, with an AM/PM indicator.
