GPIO Extension Board for Raspberry Pi
If you want to make some fun embedded computer projects with your Pi, from the first project, the most important problem you need to solve is how to breakout the Pi pins. This Extension Board help you on this, it break out all those tasty power, GPIO, I2C and SPI pins from the 26 pin header onto a this breadboard. This Extension Board is compatible with 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.
Also recommend you the 26P GPIO Ribbon Cable Wire for Raspberry Pi and Basic Bread Board to breakout the Pi pins.
