Tiny DS3231 AT24C32 I2C Precision Module Real-Time Clock Module for Arduino

The DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC) with an integrated temperature-compensated quartz oscillator (TCXO) and crystal. The device includes a battery input; disconnect the main power supply and it maintains accurate timekeeping. The integrated oscillator improves the device's long-term accuracy and reduces the number of components in the production line. The DS3231 is available in commercial and industrial temperature ranges, using a 300mil 16-pin SO-1 package. The RTC maintains seconds, minutes, hours, day, date, month, and year information. Note: This is an Arduino product, not an original. It only replaces accessories.
