Product Overview

264 is a great battery backed real time clock (RTC) that allows user 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. This breakout board is a kit and requires some light soldering which should only take about 15 minutes. The DS1307 is simple and inexpensive but not a high precision device. It may lose or gain up to 2 seconds a day. This serial real time clock (RTC) is a lowpower, full binary coded decimal (BCD) clock/calendar plus 56bytes of NV SRAM.
  • All parts including PCB and header are included
  • Quick to assemble and use, two mounting holes
  • Plugs into any breadboard, or can use wires
  • Example code and library for Arduino
  • Will keep time for 5years or more and
  • RTC counts sec, min, hrs, date, month, week day, year with leap-year compensation valid upto 2100
  • 56Byte, battery backed, general purpose RAM with unlimited writes
  • I2C serial interface and programmable square wave output signal
  • Automatic power fail detect and switch circuitry
  • Consumes less than 500nA in battery backup mode with oscillator running

ADAFRUIT INDUSTRIES - 264 - RTC BREAKOUT BOARD KIT, DS1307 5 5 1 1
easy to setup and solider I got this to add a cheap RTC to my Pi. This was very easy to solider and setup. I would recommend looking at adafruits website to get the proper modules installed. One other thing that was mentioned on there website that I will mention here is that for the Pi you don't, I repeat do NOT, install the two resistors that come with it. That makes it work at 3V instead of 5V. October 1, 2013
