AJMRTC DS3231SN V2.0 real-time clock module uses the temperature-compensated DS3231SN IC, which delivers far better timing accuracy than common DS1307 modules. It keeps tracking year, month, day, week, hour, minute and second data. It communicates via I2C bus and can directly connect with Arduino, ESP32, STM32 and Raspberry Pi. When the main power supply is cut off, the CR2032 backup battery maintains the clock running continuously. The pin header is pre-installed for convenient wiring on breadboards or PCB sockets. It is widely used for digital clocks, data loggers, timing alarm systems, smart agriculture controllers and student electronic development projects. Note that the CR2032 battery is not included.
