AJMRTC DS3231 real time clock module is widely used for adding accurate time functions to microcontroller systems. The temperature-compensated oscillator greatly reduces time drift compared with common DS1307 modules. The onboard AT24C32 4KB EEPROM can store setting parameters, event logs or calibration data without power. It uses the I2C bus so multiple IIC devices can share the same control lines. A CR2032 battery maintains the clock during power outages. It is fully compatible with Arduino, STM32, ESP32 and Raspberry Pi, a staple component for makers building data loggers, timers and automation devices.
