High Precision AT24C32 RTC Module 3.8x2.2cm with Battery & Leap Year

High Precision AT24C32 RTC Module 3.8x2.2cm with Battery & Leap Year Description

AT24C32 Module High Precision Clock Module With Battery&Leap Year Compensation
Features:

The module is a low cost, high precision I2C real time clock (RTC) with integrated temperature compensated crystal oscillator (TCXO) and crystal.


The device includes a battery input port that maintains accurate timing when the mains supply is disconnected. Integrated crystal oscillator improves long-term accuracy of the device.


Both commercial and industrial temperature ranges are being provide, adopting a 16-pin 300 mil SO package.


This product is made of ABS material, strong and durable.


This clock module also has other functions that extend the additional features and options range of the system host.
