HW-111 Real Time Clock I2C Module With Battery

Product Title: HW-111 Real-Time Clock I2C Module with Battery

The HW-111 real-time clock (RTC) IC is a unique and essential component for any electronic project. With its I2C interface and 8 pins, this DS1307-based RTC module offers a low-power solution for keeping track of time and date. It also features a battery backup SRAM of 56 bytes, ensuring that your data is safe even in the event of a power outage.

The clock/calendar function displays accurate data in seconds, minutes, hours, days, dates, months, and years. It even automatically adjusts for months with fewer than 31 days, making it a convenient and reliable choice for timekeeping. The HW-111 is also Underwriters Laboratory (UL) recognized, providing peace of mind for its quality and safety.

One of the standout features of this RTC module is its 1Hz output pin, which allows for precise timing in your projects. It consumes less than 500nA in battery backup mode with the oscillator running, making it an energy-efficient option. The DS1307 is accessed via the I2C protocol, and the module comes fully assembled and pre-programmed with the current time.

With a 56-byte non-volatile RAM for data storage and 56 bytes of non-volatile memory available to the user, the HW-111 offers plenty of space for storing important information. Its compact size of 28*27*6.4 (mm) and included CR2032 lithium battery make it a convenient and portable choice for any project. Made in China, this high-quality RTC module is a must-have for any electronics enthusiast.
