DS3231 RTC Module Precise Real Time Clock

The DS3231 RTC Module Precise Real Time Clock is a highly accurate and reliable timekeeping device that maintains precise time and date information even when the main power is turned off. Built around the DS3231 chip, this module integrates a temperature-compensated crystal oscillator (TCXO) and a real-time clock to deliver superior stability and minimal drift, making it ideal for a wide range of timing applications in electronics and embedded systems.

Key Features:

•  provides high precision with minimal deviation — typically less than ±2 ppm from 0°C to +40°C.

• Keeps track of seconds, minutes, hours, day, date, month, and year, with automatic leap-year correction until the year 2100.

• Uses an I²C interface, making it easy to integrate with popular microcontrollers such as Arduino, Raspberry Pi, ESP32, STM32, and others.

• Built-in battery backup (CR2032 slot) maintains clock accuracy when power is lost.

• Temperature-compensated crystal ensures consistent accuracy over a wide range of environments.

• Low power consumption allows long-term operation from a small coin cell battery.

• On-board EEPROM (AT24C32) for storing additional user data or configurations.

• Compact PCB design, perfect for time-based automation, data logging, and scheduling applications.

Applications:

• Real-time data logging systems.

• Alarm clocks, timers, and scheduling systems.
