Description:
The High Accuracy DS3231 RTC & EEPROM module is a precision timekeeping device designed for applications requiring accurate and reliable time management. At its core is the DS3231 real-time clock (RTC) chip, known for its high accuracy and stability, featuring an integrated temperature-compensated crystal oscillator (TCXO) that ensures timekeeping precision across a wide temperature range. This module also includes an AT24C32 EEPROM, providing 32KB of non-volatile memory for data storage, making it ideal for data logging and other applications where retaining information without power is essential.
The DS3231 RTC maintains time in seconds, minutes, hours, days, dates, months, and years, with leap-year compensation valid up to 2100. It operates via a simple I2C interface, allowing easy integration with microcontrollers such as Arduino and Raspberry Pi. The module is equipped with a CR2032 battery holder, enabling continuous timekeeping even when the main power supply is disconnected. Its compact design and dual functionality make it a versatile component for projects requiring precise timekeeping and data storage capabilities.
