AJMRTC SD3078 High Precision RTC Real Time Clock Module, Low Power Digital Clock Board, I2C Interface Time Calendar Module for Arduino Raspberry Pi Embedded MCU & Electronic DIY Projects

AJMRTC SD3078 RTC real time clock module uses SD3078 high-precision clock IC to keep accurate time, date and week information. It features ultra-low power consumption, and can continue timekeeping via backup coin cell when the main power is disconnected. The module communicates through I2C interface for easy connection with most microcontrollers. It can output year, month, day, hour, minute, second and weekday data for timestamp recording. Small PCB size makes it easy to integrate into data loggers, environmental monitoring devices and other embedded electronic DIY projects.
