public class MCP23S17Pin
extends MCP23X17Pin

This GPIO provider implements the MCP23S17 SPI GPIO expansion board as native Pi4J GPIO pins. More information about the board can be found here: * http://ww1.microchip.com/downloads/en/DeviceDoc/21952b.pdf

The MCP23S17 is connected via SPI connection to the Raspberry Pi and provides 16 GPIO pins that can be used for either digital input or digital output pins.
