Do you notice the 2 rows of 13 header pins on your Pi? Those are the General Purpose Input/Output (GPIO) pins and that's where the real fun is.
GPIO pins allow you to play around with SPI, I2C, serial UART, 3V3 and 5V power. With a little bit of programming, you can use these pins to send and receive data from external sources, running motors, playing with LEDs and so much more.
If you want to link those pins onto a breadboard or a PCB, this cable comes in handy. This nice multi-colour ribbon cable is a great addition to your project. Look closely at the connector and you will see a small triangle. This triangle denotes Pin 1. It's important to align and connect the triangle to the P1 pin on the board. Be sure to follow this convention to avoid the risk of damaging your Pi.
This product is for older Raspberry Pi Model A and B with 26 pin GPIO and not compatible with Raspberry Pi 3B+, 3B, 2B, Model A+ and Model B+ with 40 GPIO pin.
