This is a great battery-backed real time clock (RTC) that allows your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. Perfect for datalogging, clock-building, time stamping, timers and alarms, etc. The DS1307 is the most popular RTC - but it requires 5V power to work (although Adafruit have used it with 5V power and 3.3V logic successfully)
Works great with an Arduino using Adafruit's RTC library or with a Raspberry Pi (or similar single board linux computer)
Note: This product does not come with a CR1220 coin cell battery. Adafruit recommend you purchase a coin cell battery to use with this product.
The DS1307 is simple and inexpensive but not a high precision device. It may lose or gain up to 2 seconds a day. For a high-precision, temperature compensated alternative, please check out the DS3231 precision RTC. If you do not need a DS1307, or you need a 3.3V-power/logic capable RTC please check out Adafruit's affordable PCF8523 RTC breakout
