The Model B+ is equipped with a row of 2x20 pin headers. These aren't just for show however, these (General Purpose Input/Output) pins can be used to access a whole new world of fun with your Model B+. Through programming the Pi, these ports are able to undertake a variety of tasks including playing with LEDs, running motors and sending and recieving data.
So, if you want to get your interating with physcial hardware electronic systems such as a breadboard, you'll most likely want to bridge the connections with a ribbon cable and socket connector.
These cables are perfect to get hacking on your in no time! One end features a 40 Pin Female ICC Socket (that plugs into the 's port) and on the other end features individual 0.1" header female pins which clip neatly on to standard-pitch 0.1" (2.54mm) male headers. Each free contact is individually labelled 1-40 for simple, repeated identification whilst hacking! No need for a cobbler kit - just plug in, and you're away!
