Tiny RTC DS1307 Real Time Clock I2C Module

The DS1307 RTC (Real-Time Clock) Module is a compact and accurate timekeeping module used to keep track of time in electronic systems. It is based on the DS1307 IC, which provides accurate timekeeping capabilities and can operate with a battery backup to maintain time during power outages. This module is widely used in various applications including clocks, data loggers, and embedded systems.

Features:

• Accurate timekeeping with a real-time clock (RTC) IC
• Battery backup to maintain time during power loss
• Easy-to-use I2C interface for communication with microcontrollers
• Provides seconds, minutes, hours, day, date, month, and year
• Low power consumption for battery operation
• Integrated crystal oscillator for precise timekeeping
• Compact and easy to integrate into projects

Usage:

1. Connect the DS1307 RTC Module to your microcontroller via the I²C interface (SDA and SCL lines).
2. Insert a compatible lithium battery into the module to provide backup power.
3. Use the appropriate library or driver to interface with the DS1307 and set the current date and time.
4. Retrieve and update the time as needed for your application.

Caution:

• Ensure the battery is properly installed to maintain time during power outages.
• Handle the module with care to avoid damaging the crystal or solder connections.
• Verify I2C connections to avoid communication issues.
