    DS3231M is an extremely accurate I2C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator.

    Save precious cycles on your micro as the RTC maintains seconds, minutes, hours, day, date, month and year information in easy to access registers. On top of that, the DS3231M manages leap years and has two configurable alarm clocks.

    • Two programmable alarms
    • Programmable square-wave output
    • DS3231M Datasheet
    • LIR2032 / CR2032 backup battery holder for uninterrupted time management (battery not included)

      Easy to use with the Arduino but remember to remove R5 (200R) if using a non rechargeable battery such as CR2032 (Posted on 14/01/2016)
