Downgrade GPIO Ribbon Cable for Pi A+/B+/Pi 2/Pi 3/Pi 4 - 40p to 26p

by Adafruit

Oof - you got a Raspberry Pi 4 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.

Available in slimming Adafruit Black - pin #1 is marked with a white stripe!

Note: The Raspberry Pi Model A+, Raspberry Pi 2, Raspberry Pi 3, & Raspberry Pi 4 are also compatible with this product!
