Description: The PCB board uses RF-4 Class A materials, the board layout is neat, and the components are properly positioned. The LED spacing is 2cm. After many tests, this spacing is appropriate. All the key interfaces on the board are designed on the side so that it can be combined with the acrylic shell more beautifully. Features: The floor consists of a circuit board and other components of the spare parts, need their own welding. With infrared remote control debugging with acrylic shells. 42 offline animations, more than 10 minutes. 14 offline audio animations. Day / night control mode. 512 LED lights to form a square three-dimensional space, from seven kinds of brilliant mode showing a three-dimensional effect, better viewing at night.
