YwRobot DS1307 Real Time Clock RTC Module Previous 
The DS1302 Real Time Clock RTC Module provides real-time timekeeping with low power consumption and built-in memory storage. It supports seconds, minutes, hours, days, weeks, months, and years before 2100. The module can operate in 12-hour or 24-hour mode using the AM/PM indicator. Once the time and date are set, they remain stored even after power is removed. The module uses a small pin count and is suitable for electronics and automation projects that need continuous clock tracking.
