The DS1302 RTC Real Time Clock Module with CR2032 Battery is a compact electronic module used to keep accurate time in microcontroller projects (such as Arduino, ESP8266, or PIC), even when the main power is turned off.
Key Features
-
Real-time tracking: Maintains seconds, minutes, hours, day, date, month, and year.
-
Battery backup: The included CR2032 coin battery keeps the clock running during power outages.
-
Low power consumption: Designed for long battery life.
-
Simple interface: Uses a 3-wire serial communication (CLK, DAT, RST), making it easy to connect.
-
Trickle charger support: Can recharge a rechargeable backup battery (if used instead of a standard CR2032).
