Description:

This RTC DS1302 module allows you to use your Arduino or MCU to do time / date related functions such as: Starting a task at a specific date / time or recording the date / time of an event (datalogging!) or simply displaying the time / date to a user. 

The backup battery (not included, please purchase a CR2032 battery from the suggested items) makes sure that the time and date are kept accurate even if your Arduino / MCU is powered off.

Features:

  • DS1302 timing IC
  • This real time clock has the ability track second, minute, hour, day, week, month, year, and the ability to adjust a leap year
  • Wide working voltage: 2.0~5.5 V
  • When The working voltage is 2.0V, the current is less than 300nA
  • Read/write clock or RAM data have two transmission modes: Single-byte / many bytes group
  • Simple 3 line interface. Easy to install

Pin out:

  • VCC -> Vsupply (Arduino 3.3V)
  • GND -> Arduino Gnd
  • CLK ->  (SCLK_PIN)
  • DAT -> (IO_PIN)
  • RST -> (CE_PIN)

Works great using the DS1302 library written by Henning Karlsen. The library can be found at http://www.henningkarlsen.com/electronics/library.php?id=5.

Battery not included.
