Raspberry Pi B+ GPIO Details And Pinout

One of the most significant changes to the Raspberry Pi Model B+ is the 40-pin header (J8).
This offers and increase of 14 pins over the 26-pin header on the original Raspberry Pi.

Here is a diagram showing all 40-pins :

Additional GPIO
The B+ offers 9 extra GPIO pins which can be configured as inputs of outputs. This brings the total number to 26 (17+9).

Ground Pins
The extended header offers an additional 3 ground pins. So that’s a total of 8.

Referring to information on a webpage is great but when you are hardware interfacing it is still useful to be able to scribble on a piece of paper. This is a printable Model B GPIO worksheet so that you can draw and write on the diagram as you build your projects.
It makes it much easier to remember what wires, sensors and components you’ve got connected to each pin.

You can print out and keep together with Raspberry Pi B+
