DS3231 RTC Rpi Module

The DS3231 RTC Raspberry Pi Module is a high-precision real-time clock module designed to provide accurate date and time information even when the host system is powered down. Based on the DS3231 RTC chip, it incorporates a temperature-compensated crystal oscillator (TCXO) that significantly improves timekeeping accuracy compared to standard RTC solutions. The onboard backup battery maintains clock operation during power interruptions, making it ideal for Raspberry Pi, Arduino, ESP32, and other embedded systems requiring reliable time and date tracking. Its I²C interface ensures simple integration into a wide range of electronics and IoT projects.
