Microcontroller Serial to Parallel Pin IO Expansion Module 74HC595 3 to 24pin LED control

Overview

This module is an IO port expansion module consisting of three 74HC595 chips

IO port expansion module composed of three 74HC595 chips in cascade

In many simple microcontroller application systems

Often found that the microcontroller pins are not enough

This expansion module can solve your problem

The module can use three ordinary IO port driver

To achieve the expansion of 24 output ports

The main performance is serial input, well line output.

This module is suitable for all microcontrollers

It is a perfect solution to the problem of insufficient microcontroller pins.

Characteristic
