Assembled Pi T-Cobbler Plus - GPIO Breakout for RasPi A+/B+/Pi 2 is a T-shaped add on prototyping Pi Cobbler from Adafruit specifically designed for the B+ and Pi 2 that you can break out all power, GPIO, I2C and SPI pins from the 40-pin header onto a solderless breadboard. This will make "cobbling together" prototypes with the Pi super easy.
Assembled Pi T-Cobbler Plus - GPIO Breakout for RasPi A+/B+/Pi 2 is designed for use with Raspberry Pi Model A+/B+/Pi 2 only! No soldering required!
Assembled Pi T-Cobbler Plus - GPIO Breakout for RasPi A+/B+/Pi 2 is not as compact as Assembled Pi Cobbler Plus - Breakout Cable for Pi B+/A+/Pi 2, but still a less bulky way to wire up. The cable plugs between the Pi A+/B+/Pi 2 computer and the T-Cobbler breakout. The T-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.
