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.
