4pcs DS3231 AT24C32 IIC Real Time Clock RTC Memory Module PCB for Arduino S0Z6:
$10

Features:
DS3231 Module is a low-cost, extremely accurate I2C real-time clock (RTC).
With a CR2032 button cell to maintain accurate timekeeping when disconnecting the main power supply.
Integrated oscillator improves long-term accuracy of the device and reduces the number of components of the production line.
RTC maintains seconds, minutes, hours, day, date, month, and year information.
The months which have less than 31 days, their end date will be automatically corrected(including corrections for leap year).
The clock operates in either the 24 hours or band / AM / PM indication of the 12-hour format.
Provides two configurable alarm clock, a calendar and a square wave output(programmable).
IIC bus interface, the maximum transmission speed of 400KHz (working voltage of 5V).
