LED Cube Light PCB Display Kit with USB Power

Build a 3D LED Cube and See the Electronics Behind the Display

The LED Cube Light PCB Display Kit is a hands-on electronics project that lets you assemble a fully functioning 3D LED light cube from the circuit board up. Supplied with a pre-programmed printed circuit board and all required electronic components, this kit clearly reveals how timing, routing, and power control create dynamic light patterns.

The main PCB measures approximately 11.7 x 12.7 cm and is designed to support a compact cubic LED structure. A combination of resistors, capacitors, IC sockets, and driver chips work together to control red and blue LEDs in coordinated sequences. The board operates on a low, safe DC voltage of 4.5-5.5 V and connects via the included USB cable to a PC, laptop, or USB power adapter for convenient, reliable power.

Ideal for electronics enthusiasts, students, and curious makers, this kit provides both a visual showpiece and a learning platform. As you assemble each component, you gain a clearer understanding of how PCBs route power and signals, and how programmed logic translates into smooth lighting transitions. Once completed, the cube becomes a striking tabletop display, showcasing layered 3D light effects that are engaging to watch and easy to demonstrate in a classroom, workshop, or home office.
