Description

The High Accuracy Pi RTC is based on the clock chip DS3231. The DS3231 is a low-cost, extremely accurate I2C realtime clock (RTC). It provides an RTC for Raspberry Pi via the I2C interface. With the clock source from the TCXO(temperature compensated crystal oscillator), the RTC maintains seconds, minutes, hours, day, date, month, and year information. 

The date at the end of the month 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.

The clock provides two programmable time-of-day alarms and programmable square-wave output. The INT/SQW pin either generates an interrupt due to alarm condition or outputs a square-wave signal and the selection is controlled by the bit INTCN.

If you want to retain the time infomation even when the Raspberry Pi is powered off, you need to insert a 3V CR1225 lithium cell into the battery holder.
