DS3231 RTC Module Precise Real Time Clock I2C AT24C32 without cell

Product Description:
Keep your projects on time with the DS3231 RTC Module, a highly accurate real-time clock designed for microcontroller systems like Arduino, Raspberry Pi, ESP8266, and more. This module uses the DS3231 RTC chip—a temperature-compensated crystal oscillator-based timekeeper that ensures reliable timekeeping in any environment.

Integrated with AT24C32 EEPROM for additional data storage, the module communicates through an I2C interface, allowing seamless connection with most development boards. This version comes without a coin cell, making it a flexible and economical choice for projects that already include a power backup solution.
