DS3231 RTC Module Precise Real Time Clock I2C AT24C32 Without Cell

The DS3231 RTC Module is a high-precision real-time clock module designed to maintain accurate date and time information for microcontroller and embedded electronics projects.

The module uses the DS3231 real-time clock IC and communicates with a microcontroller through the I2C interface. It is suitable for Arduino, ESP32, ESP8266, STM32, Raspberry Pi and other development platforms.

The module can maintain time information when the main power supply is interrupted when an appropriate backup cell is installed.
