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 Operating voltage range: 2V-6V Single I0 port output current up to 30mA
