RTC 1302 Real Time Clock Module
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)
