Here is a real time clock based on the DS3234 Real Time Clock IC. The DS3234 is a low-cost, extremely accurate SPI bus real-time clock with an integrated temperature-compensated crystal oscillator and crystal.
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 of leap year. The clock operates in either the 24-hour or 12-hour format with AM/PM indicator. Two programmable time-of-day alarms and a programmable square-wave output are provided.
The underside of the board holds a 12mm coin-cell battery holder for battery backup.
Note: These do not include a battery. See the related products below for a battery.

這裡是一個基於DS3234實時時鐘IC中的實時時鐘。該DS3234是一款低成本,高精度SPI總線實時時鐘集成了溫度補償晶體振盪器和晶體。
RTC保存秒,分鐘,小時,星期,日期,月份和年份信息。在每月的月末日期自動少於31天,包括閏年的修正調整好幾個月了。時鐘可以通過AM / PM指示器工作在24小時或12小時格式。提供了兩個可編程日曆鬧鐘和一個可編程方波輸出。
電路板的底面適用於備用電池12mm的鈕扣電池座。
