Raspberry Pi board is NOT included in this kit. Great for testing circuits before committing them to a more permanent board and planning out a bigger project. This kit will make your Raspberry Pi more flexible and easy to build with other sensors for many experiments. The rainbow ribbon, jumper wires and T-type connector board are really handy for getting the GPIO header to a breadboard for your creations. This is a Raspberry Pi GPIO extender kit that provides a way to easily connect your Raspberry Pi 4B/3B+/3B/ 2B/ 1B+ to a breadboard. This can be convenient for you to do experiments related to Raspberry Pi, and can avoid damage to the Raspberry Pi motherboard due to frequent use of Raspberry Pi GPIO.
