Do you notice the 2 rows of 20 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 a best practice to align and connect the triangle to the pin 1 near J8 mark on the board. Be sure to follow this convention to avoid the risk of damaging your Pi.
This product is for Raspberry Pi 3B, 2B, B+ and A+ with 40 GPIO pins. It is not compatible with older Raspberry Pi Model A or B with 26 GPIO pins
It could also work with other Single Board Computers with similar form factor such as the Odroid-C2/C1+.
