    Description

    This module is specially designed for IO expansion Modules. It can effectively solve the problem, which is for Raspberry that can't send IO port sufficiently. And module uses four 74HC595 chips to expand 32 IO ports. As shown above, the top of the module will expand the IO for again that can be cascaded for more IO expansion modules to achieve theoretically unlimited expansion.
    Features:
    32 GPIO Expansion - This cascade expansion board supports 32 GPIO expansion.
    Connection - The IO extend adapter module is capable of connecting with same module infinitely.
    Wiring PI API & Sample - It uses wiring PI API and sample .
    Stable Connection - SPI interface ensures the stability and smoothness of connection.
    8-bit Input & Output - Adopting 8-bit serial input and 8-bit serial serial or parallel output to make data transmission super stable without stuck or cut.
    Port:
    -- for  2*13port
    -- for  2*13 cascade port
    --Q0-Q31 expanded IO port
    Specifications:
    Working voltage: 2.4v-5v
    IO voltage: 3.3v
    Expanded 32 unidirectional IO
    Connection through SPI
    100 MHz( typical) out frequency
    8-bit serial input
    8-bit serial or parallel output
    Specified from -40C to +85C and from -40C to +125C
    Typical Application: Drive the lattice screen, Driver numeric display, Drive LED
    How to Use:
    Insert the module that the silk screen says 'RPI IN'. Pay attention that don't make the direction reversed. The correct direction of insert module is above the for 's PCB; The 8*4header in the module are Q0-Q31 expanded GPIO, they can connect to the peripheral through the Line. The header which near silk screen write 'EXT' expand GPIO for , user can cascade the other module or the same module.
