This is the assembled version of the Pi T-Cobbler Plus. It only works with the Raspberry Pi Model Zero, A+, B+, Pi 2,Pi 3 The Raspberry Pi has landed on the Maker World like a 40-GPIO pinned, quad-USB ported, credit card sized bomb of DIY joy. And while you can use most of our great Model B accessories by hooking up our downgrade cable, its probably a good time to upgrade your set up and accessorize using all of the 40 pins. The T-Cobbler Plus is an add on prototyping board specifically designed for the 2×20 connector-type Raspberry Pi, and can break out all those tasty power, GPIO, I2C and SPI pins from the 40-pin header onto a solderless breadboard. This set will make cobbling together prototypes with the Pi super easy. Each order comes with a 40 pin ribbon cable and assembled T-Cobbler Plus. You can plug the 40-pin GPIO cable between the Pi computer and the T-Cobbler breakout. You can plug the 40-pin GPIO cable between the Pi computer and the T-Cobbler breakout. The T-Cobbler can plug into any solderless breadboard (or even a prototyping board like the PermaProto). The T-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.
