Raspberry Pi GPIO Expansion Module

$31.97

Part Number:  SS-114990169
Brand:  Seeed Studio Australia

This module is designed specifically for the Raspberry Pi B+/A+ IO expansion modules, which can effectively solve the Raspberry send IO port insufficient. Module uses four 74HC595 chips to expand 32 IO ports. As shown above, the top of the module will expand the IO of Raspberry Pi again that can be cascaded for more IO expansion modules can theoretically unlimited expansion.
