₹255.00 (Excluded Tax)
Total price: (Tax : )

Description:
The DS3231 RTC Module is a high-precision real-time clock board with built-in temperature-compensated crystal oscillator (TCXO). It maintains accurate time and date even during power loss using a backup battery, making it ideal for clocks, data logging, and time-based automation in STEM projects.

Specifications:

  • Type: Real-Time Clock (RTC) Module
  • RTC IC: DS3231
  • Communication Interface: I2C
  • Operating Voltage: 3.3V – 5.5V
  • Time Format: Seconds, Minutes, Hours, Day, Date, Month, Year
  • Accuracy: ±2 ppm (high precision)
  • Onboard Crystal: Temperature compensated (TCXO)
  • Backup Battery: 3V Coin Cell (CR2032)
  • Additional Memory: 24C32 EEPROM (varies by module)
  • Mounting: PCB module with header pins

Features:

  • High accuracy timekeeping
  • Built-in temperature compensation
  • Battery backup support
  • I2C interface (uses fewer pins)
  • Stable and reliable performance

Applications:

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

Pin Identification:

  • VCC → Power supply
  • GND → Ground
  • SDA → I2C Data
  • SCL → I2C Clock

Important Note:

  • Insert CR2032 battery for backup operation
  • Default I2C address is usually 0x68
  • Much more accurate than DS1307
  • Ensure correct time initialization via code

Package Includes:

  • 1 × DS3231 RTC Module Board
  • 1 × CR2032 Battery (may vary by kit)
