DS1307 Real Time Clock (RTC) Module
Description:
DS1307 Real-Time Clock (RTC) Module is a widely used timekeeping module that provides precise time and date functionality to embedded systems and microcontroller-based projects. Built around the DS1307 RTC IC from Dallas Semiconductor (now part of Maxim Integrated), this module enables microcontrollers like Arduino, Raspberry Pi, and other systems to accurately keep track of time, even during power outages, thanks to its integrated battery backup.
Features:
1. I2C Communication Protocol
2. Real-Time Clock with Date and Time
3. Battery Backup
4. Low Power Consumption
5. Timekeeping for Both 12-Hour and 24-Hour Formats
6. Alarm and Square-Wave Output
7. Easy to Interface and Use
8. Compact Size
