Since I have been using model B+ and model 2 a lot lately, I wanted an updated GPIO pinout diagram. Also, since I used WiringPi, the diagram had to include that numbering scheme. None of the diagrams I found satisfied me, so I made my own. I used the output from the WiringPi command gpio readall and did some formatting in excel to produce the following diagram. I hope you find it useful.
