Real Time Clock Module (RTC)- DS1302 WithOut Battery

Description

DESCRIPTION : 

This RTC DS1302 Real Time Clock 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 or simply displaying the time / date to a user.

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)
