The SmartElex DS3231 RTC Module with EEPROM is a high-precision RTC module designed for accurate date and time tracking in embedded systems and IoT projects. Based on the DS3231 chip with an integrated temperature-compensated crystal oscillator (TCXO), this I2C RTC module ensures stable and reliable timekeeping across temperature variations.
It features an onboard 32Kbit AT24C32 EEPROM for non-volatile data storage, along with 1Hz SQW and 32KHz outputs for timing applications. Operating within an exact voltage range of 2.2V to 5.5V, the module maintains time even during power loss using a backup battery, making it ideal for data loggers, automation systems, and time-critical electronics projects.
