Description
Product Description
The DS1302 Real-Time Clock (RTC) Module is a timekeeping module designed to track time and date in electronic projects. It uses the DS1302 RTC chip to maintain seconds, minutes, hours, day, date, month, and year information.
The module communicates with a microcontroller using a simple 3-wire serial interface, making it suitable for Arduino and other compatible embedded systems. It can be used in digital clocks, time-based automation, data logging, attendance systems, and other projects that require timekeeping.
This product is supplied without a battery, so a compatible backup battery may need to be purchased separately if the board supports battery backup.
