## Description

Now that you've finally got your hands on a Raspberry Pi® , you're probably itching to make some fun embedded computer projects with it. What you need is an add on prototyping Pi T-Cobbler from Adafruit, which can break out all those tasty power, GPIO, I2C and SPI pins from the 26 pin header onto a solderless breadboard. This mini kit will make "cobbling together" prototypes with the Pi super easy. Designed for Raspberry Pi Model B Revision 1 or Revision 2.

This Cobbler is in a fancy T-shape, which is not as compact, but is a little easier to read the labels. [We also have the more compact original Cobbler.](https://core-electronics.com.au/adafruit-assembled-pi-cobbler-breakout-cable-for-raspberry-pi.html)

The Pi T-Cobbler mini kit comes with a [26 pin ribbon cable](https://core-electronics.com.au/gpio-ribbon-cable-for-raspberry-pi.html), a custom PCB, ribbon cable socket and header pins. A little soldering is required to put it together but its really easy, even a beginner can do it in 15 minutes so please click to read the tutorial For plug-and-play fans, [We also have an assembled version here.](https://core-electronics.com.au/adafruit-assembled-pi-t-cobbler-breakout-for-raspberry-pi-11800.html)

Once soldered together, the cable plugs between the Pi computer and the T-Cobbler breakout. The T-Cobbler can plug into any [solderless breadboard](https://core-electronics.com.au/full-sized-breadboard.html) (or even a prototyping board like the [PermaProto](https://core-electronics.com.au/adafruit-perma-proto-super-pack.html)). 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.

The Adafruit Pi T-Cobbler is compatible with Model A and Model B both versions 1 and 2 of the Raspberry Pi Computer - for version 2 computers, note that the GPIO #21 has been replaced with GPIO #27 and that the I2C pins are now I2C port #1 instead of #0. All other pins are the same. **This Cobbler is not compatible with the Model B+** unless you have [a GPIO downgrade cable](https://core-electronics.com.au/downgrade-gpio-ribbon-cable-for-raspberry-pi-model-b-40p-to-26p.html)

**Please note, this kit only contains a [26 pin ribbon cable](https://core-electronics.com.au/gpio-ribbon-cable-for-raspberry-pi.html), a custom PCB, ribbon cable socket and header pins.** A Raspberry Pi, breadboard, [breadboarding wires](https://www.adafruit.com/images/ID0153.jpg), cables, components, [case](https://core-electronics.com.au/adafruit-pi-box-enclosure-for-raspberry-pi-model-a-or-b.html), power supply, etc is not included! we do stock many of those items in the shop, so check those out as well!

What is the Raspberry Pi® ? A low-cost ARM GNU/Linux box.

The Raspberry Pi® is a single-board computer developed in the UK by the Raspberry Pi Foundation with the intention of stimulating the teaching of basic computer science in schools. The design is based on a Broadcom BCM2835 system on a chip (SoC), which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU, and 256 megabytes of RAM. The design does not include a built-in hard disk or solid-state drive, instead relying on an SD card for booting and long-term storage. The Foundation plans to support Fedora Linux as the initial system software package/distribution, with support for Debian and Arch Linux as well - Wikipedia.

Raspberry Pi® is a trademark of the Raspberry Pi Foundation.
