Oof – you got a Raspberry Pi Model B+ that you want to have work with some old kit or plate or breakout or something and it uses the classic 26-pinout. Very frustrating, it is…unless you have this ingenious ‘downgrade’ GPIO cable. It has a 40-pin socket on one end, but only the first 26 pins have a cable and the other end matches any sort of Cobbler or PermaPi or what-have-you.
Cable is 6″ long, and pin #1 is marked with a white wire. This cable is not compatible with the Raspberry Pi Model A or B – It’s for the B+ only!
Available in slimming Adafruit Black – pin #1 is marked with a white stripe!
That new Raspberry Pi® Model B+ 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.
This cable is not compatible with the Raspberry Pi Model B or Model A!
If you want to bridge those contacts out onto another PCB, you’ll want this cable! It’s 6″ long and has 40 socket & wire sets. Pin #1 is marked with a white wire.
It’s available in custom Adafruit Black and is an essential accessory for getting started with your brand new B+!
