GPIO Ribbon Cable for Raspberry Pi
Including €0.02 for ecotax
That new Raspberry Pi board has just a row of 2x13 pin headers soldered on - those are the GPIO (general purpose input/output) pins. 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.
If you want to bridge those contacts out onto another PCB, you'll want this cable! It's 6" long and has 26 socket & wire sets. Pin #1 is marked with a white wire. If you have one of our nice Clear Case for Raspberry Pi Board, you can even have this plugged in while the case is closed by passing the ribbon cable through the slot on the side.
This article is compatible with version B the Raspberry Pi board, it is not compatible with version B+ or Raspberry Pi 2.
