Raspberry Pi has a 40 Pin GPIO header to interact with Real World. But it is not that simple to connect circuits to RPi on that 40 pin header. This is simplified using this T-Cobbler board. This T-Cobbler board basically brings out the pins from the Raspberry Pi to breadboard where you can easily make your own circuit to be connected to RPI.
The T-Cobbler is an add on prototyping board specifically designed for the Pi 3, 2 Model B, B+ & Zero accessories that 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.
You can plug the 40-pin GPIO cable between the Pi computer and the T-Cobbler breakout. The T-Cobbler can plug into any solder-less breadboard.
