NEW PRODUCT – DS1307 Real Time Clock breakout board kit $9.00
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, and works best with 5V-based chips such as the Arduino.
All parts including PCB, header and battery are included
Quick to assemble and use
Plugs into any breadboard, or you can use wires
We have example code and library for Arduino with a walkthrough on our documentation page
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 ChronoDot.
