The Pi Cobbler mini kit comes with a 26 pin ribbon cable, a custom PCB, ribbon cable socket and header pins. A little soldering is required to put it together but its really easy, even a beginner can do it in 15 minutes so (notify us to solder for you if you like), the cable plugs between the Pi computer and the Cobbler breakout. The Cobbler can plug into any solderless breadboard (or even a prototyping board like the PermaProto). The Cobbler PCB has all the pins labeled nicely so you can go forth and build circuits without keeping a pin-out printout at your desk. We think this will make it more fun to expand the Pi and build custom circuitry with it.
The Adafruit Pi Cobbler is compatible with both versions 1 and 2 of the Raspberry Pi Computer - for version 2 computers, note that the GPIO #21 has been replaced with GPIO #27 and that the I2C pins are now I2C port #1 instead of #0. All other pins are the same.
Please note, this kit only contains a 26 pin ribbon cable, a custom PCB, ribbon cable socket and header pins. A Raspberry Pi, breadboard, breadboarding wires, cables, components, case, power supply, etc is not included!
