This is a very beautiful screw terminal expansion board. The pin of 40Pin has been expanded, and the side provides a good screen prompt and LED light display. Through the fixation of the screw terminal, your wire is not easy to fall off, and be very stable. During the electronic experiment, everyone can easily connect, and there is GPI0 pin arrangement information on the top and side of the terminal. The LED lights of colors can display the status information of pins, and display different types of pin status through different colors. For example, the 5V power light is red, while the 3.3V power light is pink, the indicator light of the special function pin is dark blue, and the indicator light of GPI0 pin is light blue. You can determine whether the pin configuration is valid by observing.
