Diymore DS3231 AT24C32 IIC RTC Module Clock Timer Memory Board Beats DS1307 Without Battery

• The DS3231M is available in the same footprint as the popular DS3231 RTC. The RTC maintains seconds, minutes, hours, day, date, month, and year information.
• Two programmable time-of day alarms and a 1Hz output are provided. Address and data are transferred serially through an I2C bidirectional bus.
• Complete Clock Calendar Functionality Including Seconds, Minutes, Hours, Day, Date, Month, and Year, with Leap-Year Compensation Up to Year 2100.
• A precision temperature-compensated voltage reference and comparator circuit monitors the status of VCC to detect power failures, to provide a reset output, and to automatically switch to the backup supply when necessary.
