₹49.00 (Excluded Tax)
Total price: (Tax : )

Description:
The DS1307 RTC Module is a real-time clock board used to keep track of current time and date even when the main power is off. It uses an onboard battery backup to maintain accurate timekeeping, making it ideal for clocks, data logging, and embedded STEM projects.

Specifications:

  • Type: Real-Time Clock (RTC) Module
  • RTC IC: DS1307
  • Communication Interface: I2C
  • Operating Voltage: 5V
  • Time Format: Seconds, Minutes, Hours, Day, Date, Month, Year
  • Backup Battery: 3V Coin Cell (CR2032)
  • Accuracy: Moderate (depends on crystal)
  • Onboard Crystal: 32.768 kHz
  • Additional Memory: 56 bytes NV SRAM
  • Mounting: PCB module with header pins

Features:

  • Keeps time even during power loss
  • I2C communication (uses fewer pins)
  • Onboard battery backup
  • Simple interfacing with microcontrollers
  • Compact and easy to use

Applications:

  • Digital clocks
  • Data logging systems
  • Time-based automation
  • Alarm systems
  • IoT and embedded projects

Pin Identification:

  • VCC → Power supply (5V)
  • GND → Ground
  • SDA → I2C Data
  • SCL → I2C Clock

Important Note:

  • Not highly accurate compared to DS3231 (may drift over time)
  • Requires CR2032 battery for backup
  • Use I2C pull-up resistors if not onboard
  • Ensure correct time initialization in code

Package Includes:

  • 1 × DS1307 RTC Module Board
