Back-Compatibility Note - The GPIO Pin area is now 40 pins long however the first 26 pins are identical to the Model B to provide 100% backward compatibility for your projects. The B+ also includes the same CSI port for the camera module, and is compatible with the same operating systems (Raspian, OpenELEC, OSMC etc.). The new Model B+ also requires a 5V 2A or greater power supply for best results (which we stock separately!) Raspberry Pi - Model B+ [Discontinued]
