RTC 3231 Module is a high-accuracy real-time clock module designed to maintain precise time and date tracking in embedded and microcontroller-based systems. It is based on the DS3231 RTC chip, which features an integrated temperature-compensated crystal oscillator (TCXO) for improved accuracy compared to standard RTC modules.
The module communicates via the I²C interface and includes a backup battery holder to keep time running even when main power is removed. It provides detailed time data including seconds, minutes, hours, day, date, month, and year with automatic leap-year adjustment.
