That new Raspberry Pi® Model B+ computer you just got has a row of 2x20 pin headers soldered on - those are the GPIO (general purpose input/output) pins and for those of us who like to hack electronics they are where the real fun is. By programming the Pi, you can twiddle those pins high or low, send and receive I2C and SPI data, and access the 3V and 5V power rails.

This cable is not compatible with the Raspberry Pi Model B or Model A!

If you want to bridge those contacts out onto another PCB, you'll want this cable! It's 6" long and has 40 socket & wire sets. Pin #1 is marked with a white wire.

It's available in custom Adafruit Black and is an essential accessory for getting started with your brand new B+!

Note: The Raspberry Pi Model A+, Raspberry Pi 2 and Raspberry Pi 3 are also compatible with this product!

 

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.
Headers
Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.
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.
PCB
A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
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.
