Numbering Scheme

PI4J uses an abstract pin numbering scheme to help insulate software from hardware changes.
P14J implements the same PIN number scheme as the Wiring Pi project. More information on the WIRINGPI PIN number scheme can be found here:http://wiringpi.com/pins/

PI4J provides a Raspipin enumeration that's used to manage the accessible GPIO pins.

Expansion Header

The Raspberry Pi Model B + board contains a single 40-pin expansion headers labeled as ' J8 ' providing access to + GPIO pins .
(Pins 1, 2, Max & also labeled below.)

J8 pinout (40-pin Header)

The diagram below illustrates the Gpio pinout using the PI4J/WIRINGPI gpio numbering scheme.
