The original Raspberry Pi Model A/B computer had just 26 pins - a row of 2x13 pin headers soldered on. These are the GPIO (general purpose input/output) pins that you can use to connect to other components like sensors and LEDs.
If you want to break those contacts out onto a PCB, you'll want this cable! It's ~170mm long and has 26 socket & wire sets. Pin #1 is marked with a white wire.
Not compatible with the Raspberry Pi 4, 3B+, 3, 2 or B+. This is for the original 26-pin Raspberry Pi!
