Microcontroller Serial To Parallel Pin IO Expansion Module 74HC595 Output Port Expansion 3 To 24pin LED Control

Description

About:

This module is an IO port expansion module composed of three 74HC595 chips cascade, in many simple single-chip microcomputer application system, often find that the pin of the single-chip microcomputer is not enough, this expansion module can solve the trouble for you, the module can use three ordinary 10-end drivers, to achieve the expansion of 24 output ports mainly for serial input, parallel output. This module is suitable for all the single chip microcomputer is very perfect to solve the problem of insufficient single chip microcomputer pin.

1. Working voltage range: 2V~6V

2. The output current of a single I/O port can reach 30mA
