【LED Cube Kit】: This is a 5x5x5 LED cube, consisting of 125 LED beads. Each LED has four pins, and every LED is capable of emitting full-color light. There's no complex circuitry involved, no extra components—only four ports: VCC, GND, INPUT, and OUTPUT. 【Easy Assembly】: The PCB mainboard and LED lights come pre-soldered and tested. It's as simple as assembling the components to get it up and running. You can create a rectangular shape or achieve solder-free assembly by using various types of jumper wires. 【Program Customization】: You can program it yourself to achieve the effects you desire. All the LED signals on the unit board are connected in series, utilizing a single-wire protocol for control. This allows you to freely manipulate the color and brightness of each individual LED. 【Wide Compatibility】: With straightforward wiring and easy control, once assembled, it can output vibrant full-color LED lighting. It's compatible with programmable controllers like Arduino, Raspberry Pi, Teensy, T1000S, K1000C, and more. 【Applications】: It can be used as a desktop display kit or given as a creative gift to others. It's an imaginative and unique present choice.
