  • 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 we've used it with 5V power and 3.3V logic successfully)

    Works great with an Arduino using our RTC library or with a Raspberry Pi (or similar single board linux computer)

    • PCB & header are included
    • Plugs into any breadboard, or you can use wires
    • Two mounting holes
    • Will keep time for 5 years or more

    Note: This product does not come with a CR1220 coin cell battery. We 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 our affordable PCF8523 RTC breakout
