Description:
The DS3231 Module is a breadboard-friendly, extremely precise I2C real-time clock (RTC) module. It is designed using the DS3231 RTC chip and AT24C32 EEPROM, integrated with a temperature-compensated crystal oscillator for enhanced accuracy. The module also features a built-in comparator to monitor VCC status, detect power failures, and automatically switch to backup power supply. The AT24C32 EEPROM provides 32,768 bits of serial non-volatile memory (32Kb), organized as 4096 words of 8 bits each. This allows you to store data for your projects, even when power is lost. The DS3231 module is compatible with Arduino boards, Raspberry Pi, and a wide range of microcontrollers.
