The 32 GPIO board provide 32 channel digital expansion board designed for use on the Raspberry Pi.

 The board is based around the MCP23017 16-bit I/O expander from Microchip Technology Inc.


A pair of MCP23s17 expanders are included on the board allowing you to connect up to 32 digital 

inputs or outputs to the Raspberry Pi. The 32 GPIO Board is powered through the host Raspberry Pi 

using the GPIO port and extended pins on the GPIO connector allow you to stack the 32 GPIO along with other expansion boards.
