That new Raspberry Pi computer you just got has a row of 2×20 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.
If you want to bridge those contacts out onto another PCB, you'll want this cable! It's 20cm long and has 40 socket & wire sets.
Extra-long and bendy, this is just like your classic Pi GPIO cable but 12″ (300mm) long and fitted through a tube so that it’s a little more flexible in all directions.
Please note: These cables come with strain-relief clips that make the connector a bit taller than ‘classic’ GPIO cables. If you want to fit the cable into a Pi enclosure you may need to remove the top clips by cutting them off gently with diagonal cutters/nippers and pulling the plastic off.
Give your Pi some reach with this GPIO extender cable, which has two matching connectors on the end of a 12″ (300mm) long gray cable. Plug one end into your Pi and the other end will have a boxed male header you can plug in a Pi Plate that is expecting to go onto a Pi. This cable is not compatible with the Raspberry Pi Model B+.
