Transitioning from the Model B to the new B+ poses new challenges.
1) Memory card type is different. My old SD card that I'm using for the Model B could not be used, since the new model only uses Micro-SD card. Migrating data over from one storage card to another is time consuming.
2) Due to the new 40 pin GPIO, the Adafruit Cobbler Kit for the Model B cannot work with the new model. Adafruit has introduced the new Cobbler Kit Plus that is dedicated to the new 40-pin layout of the B+ and has brand new layout with new schematics and functionality.
However, for users who still owns the old Cobbler Kit, Adafruit provides a way to resolve this. They introduced a special GPIO cable that downgrades the 40-pin connection to the 26 pin connection so that they can connect to the old 26 pin Cobbler Kit.
For those out there interested in knowing the difference between the old and new Cobbler Kit schematics, the pictures are down below: (Top is New) (Bottom is old)
