Description

The RTC (Real-Time Clock) Module based on the DS3231 is a high-precision clock module designed to maintain accurate time and date information even when the main power is removed. It features an integrated temperature-compensated crystal oscillator (TCXO) and a backup battery holder to ensure continuous timekeeping. The module communicates via the I²C interface, making it ideal for Arduino, ESP32, ESP8266, STM32, Raspberry Pi, data logging, automation, and IoT applications.
