(Detailed Introduction)

Product Introduction

This module primarily utilizes the real-time clock chip DS1307. It is an I2C bus interface real-time clock chip launched by Dallas Semiconductor (USA). It can operate independently of the CPU, unaffected by the CPU's main crystal oscillator and its capacitors, and features accurate timing with a monthly cumulative error generally less than 10 seconds.

The chip also has a clock protection circuit for situations where the main power supply fails. The DS1307's clock is maintained by a backup battery, which prevents the CPU from accessing it for reading and writing. Additionally, it has an automatic backup power supply switching control circuit, thus ensuring accurate system clock timing even when the main power supply fails or in other harsh environmental conditions.

Explanation

Core Component: DS1307 real-time clock chip, a widely used RTC chip in electronics due to its reliability and I2C bus compatibility.
Key Features: Independent operation from the CPU, accurate timing with low cumulative error, and backup power protection to maintain timekeeping during main power outages. It is commonly used in Arduino and other microcontroller projects for applications requiring precise time tracking, such as data logging, time-stamped events, and automated systems.
Versions: The module is available in unhoused (bare circuit board) and housed (with a protective casing) options, catering to different needs for durability and integration in projects.
