The GPIO extension kit used for extending the GPIO interface on Raspberry Pi B+, it helps you break out all those tasty power, GPIO, I2C and SPI pins from the 40 pin header of Raspberry Pi B+ onto a breadboard.
There is also the GPIO board and GPIO Cable for the Model B.

Jargon buster
Plain-language definitions for the technical terms used above.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
