Do you know how is the cool advertising display made? It is exactly composed of these small RGB LED matrix. If you want to make a similar display, this RGB LED matrix will meet you need. The 8x8 LED matrix has 32 of pins, you may need a driver to control it. It sounds quite complex, but don't worry, we have provided a driver board Rainbowduino for this LED matrix as your reference. Make it easy for you to start your project.
