Step into the future of timekeeping with Kunkune’s DS3231, a state-of-the-art I2C real-time clock (RTC). Designed for precision and efficiency, this module is a must-have for every electronics enthusiast and professional in the UK.

DS3231 Key Features:

  • Precision Timekeeping: With an integrated temperature-compensated crystal oscillator (TCXO) and crystal, DS3231 ensures you’re always on time.
  • Battery Backup: Never lose track of time during power failures, thanks to its battery input that seamlessly switches when the main power is disconnected.
  • Integrated Oscillator: Reduces production line components and enhances the device’s long-term accuracy.
  • Versatile Use: Available in both commercial and industrial temperature ranges in a compact 16-pin 300mil SO package.
  • Smart Calendar: Automatically adjusts for months with less than 31 days and even accounts for leap years.
  • Dual Alarm & Square Wave Output: Set two configurable alarms and access a calendar-set square wave output.
  • I2C Bidirectional Bus: Ensures smooth address and data transfer.
  • Manual Reset: The /RST pin allows for manual system reset, giving you more control.
  • Advanced Features: From a precise digital temperature sensor to on-chip power supply control, DS3231 is packed with features that extend system host capabilities.

DS3231 Module Specifications:

  • Dimensions: 38mm (L) x 22mm (W) x 14mm (H)
  • Weight: 8g
  • Operating Voltage: 3.3V – 5.5V
  • Clock Accuracy: Within the 0-40°C range, accuracy is 2ppm, roughly equating to a 1-minute error.
