/**
 * 
 * This GPIO provider implements the Olimex AVR-IO-M-16 expansion board as native Pi4J GPIO pins.
 * More information about the board can be found here: *
 * https://www.olimex.com/Products/AVR/Development/AVR-IO-M16/
 * 
 *
 * 
 * The Olimex AVR-IO board is connected via RS232 serial connection to the Raspberry Pi and provides
 * 4 electromechanical RELAYs and 4 opto-isolated INPUT pins.
