The DS3231 AT24C32 RTC Module is a highly accurate real-time clock module equipped with a temperature-compensated crystal oscillator (TCXO) and built-in 32KB EEPROM. It keeps track of seconds, minutes, hours, day, date, month, and year with leap-year compensation and includes a backup battery slot for timekeeping even when power is lost.
Ideal for time-sensitive applications in data logging, alarms, and IoT systems, this module is a reliable solution for any microcontroller-based project.
