覆盆子 Pi GPIO 擴展模組
資料來源：https://www.seeedstudio.com/Raspberry-Pi-GPIO-Expansion-Module-p-2280.html
Description
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.
