The 64 GPIO board provide 64 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 MCP23017 expanders are included on the board allowing you to connect up to 64 digital 

inputs or outputs to the Raspberry Pi. The 64 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 64 GPIO along with other expansion boards.
