GPIO Expansion Module 8-bit IO Input & Output Board for

Descriptions:This module is specifically designed for the IO expansion module, which effectively solves the problem that Raspberry cannot fully send IO ports. The module uses four 74HC595 chips to expand 32 IO ports. As shown in the figure above, the top of the module will expand the IO of the again, which can cascade more IO expansion modules to achieve theoretical unlimited expansion. Feature: This cascade expansion plate supports 32 GPIO expansion. The IO Expansion Adapter Module is able to connect the same modules infinitely. It uses the connection PI API and sample code. The interface guarantees the stability and fluency of the connection. 8-bit serial input and 8-bit serial or parallel output make data transfer extremely stable with no breaks. Port: Raspberry π2 * 13 port e 2*13 cascade port Q0-Q31 extended IO port Specification:Working voltage: 2.4 -5V Input and output voltage: 3.3V Extended 32 one-way IO Connection through 100mhz (typical) removal frequency 8-bit serial input 8-bit serial or parallel output Specified from -40℃ to +85℃ and from -40℃ to +125℃ Application: drive grid, drive numerical display, drive matrix LED How to use: Insert the module that displays “RPI IN” on the silk screen. Be careful not to reverse the direction. The correct orientation of the plug-in module is on the 's PCB; the 8*4header in the module is a Q0-Q31 extended GPIO that can be connected to peripherals via the line. The title of "EXT" is written next to the screen to expand the GPIO of the . Users can cascade other modules or the same module. Package Included:1 * GPIO expansion module
