Pi Cobbler for the Raspberry Pi (via adafruit)
Perfect example of finding a demand and filling it.
The Raspberry Pi makes building your own computing projects conveniently simple and has the potential for endless applications. Among its great features, it gives the user a set of 26 I/O pins to use along with I2C and SPI components as well as GPIO and power pins.
To make management of these 26 pins a breeze, Adafruit has released a way to neatly direct the pics into a familiar breadboard from which all of the RPi’s capabilities can be exploited. The Pi Cobbler does not regulate or separate voltages. This must be done by the developer using buffers or other methods.
This connector piece is appropriately called the Pi Cobbler. It can break out all of those GPIO, I2C and SPI pins using a neat ribbon cable and an easy to assemble set up. The entire cobbler consists of a custom PCB, ribbon cable socket, header pins and the 26 pin ribbon cable itself. The Pi Cobbler requires a bit of assembly but it is nothing to fear with the help of a soldering gun and solder. The header pins and the ribbon socket must be soldered to the PCB to complete the device and easy to follow directions are provided on the adafruit website.
Once the Pi Cobbler is done cookin, the ribbon can be connected to the 26 pin I/O socket on the RPi, while the header pins are placed inside of a solderless breadboard where each clearly marked pin can be used for its separate purpose.
For just $7.95, the Pi Cobbler can help you untangle and better organize your projects set up.
