RGB is LED Unit include 3 individual LEDs. It is also one of the Unit from M5GO Kit. Each one can display anycolor based on RGB value. One feature of this Unit is extension, which means you can have mutiple of them wired together.
This is a very useful piece on STEM class, students can program it to realize some of cool applications, for example a traffic light.
