  • HW-111 Real Time Clock I2C Module With Battery

    151.00

    The HW-111 real-time clock (RTC) IC has an I2C interface and has 8 pins. The HW-111 (DS1307) is a low-power clock/calendar with a battery backup SRAM of 56 bytes. The clock/calendar displays qualified data in seconds, minutes, hours, days, dates, months, and years. Each month’s end date is automatically adjusted, especially for months with fewer…

  • PCF8563 I2C Real Time Clock RTC Module

    107.00

    his is an HW-689 PCF8563 Real-time Clock RTC module. It has a variety of functions, including an external programmable clock output, an alarm, a timer, features, external quartz, and a backup battery. The PCF8563 RTC Board provides a real-time clock function that is powered by an onboard battery and operates independently even when the MCU is turned off. I2C real-time clock (RTC) is less expensive and more precise than the DS1302 or DS1307. Features High Accuracy Low Power Consumption Can be interfaced with Arduino Low Cost I2C Real Time Clock (RTC) Pinout:  Pin-1: INT…
