Battery-backed Real Time Clock (RTC) - so your microprocessor project always knows what time it is. The time is preserved thanks to the battery, even without (mains) power!
The DS1307 used is the most well-known RTC and works great with 5V boards like the Arduino.
The board comes fully assembled; only the headers need to be soldered if necessary.
The battery (CR1220) is not included and must be purchased separately.
Size:
P.S. While the 1307 is inexpensive, it is not highly precise - deviations of 2 seconds per day are possible. For a more accurate clock, please check out the DS3231 Precision RTC.
