The Cube is a USB powered, smart RGB LED Cube kit, with a serial command interface for direct control and learning, an open source driver library and an on-board Arduino compatible MCU running the whole show!

The Cube was designed using the open source KiCad schematic and pcb design package:

The schematic pages have been carefully laid out to make it easy to follow and learn about a larger microcontroller based project design in operation.


  • Power and control by USB commands straight from your computer (Windows, Mac or Linux)
  • Expansion port connector for sensors, joysticks, game and interface add ons
  • Onboard ATmega32u4 MCU (Arduino Leonardo compatible)
  • USB interface for uploading new sketches and sending serial commands
  • Arduino driver library with example programs and animations at:
  • Includes ZigBee/XBee headers so you can add a wireless module (not included)
  • Prototyping area with I2C, power and spare pins next to it

This project is made up of 3 schematic and pcb project folders. Each folder within this repository includes a handy copy of the schematic in PDF format and image(s) of the main pcb.


The design is saved as a KiCad project. KiCad PCB design software is available from free and open-source. To use this project download it and place the directories containing these files into the a folder on your computer. Then open KiCad and navigate to the *.pro (project) file for each section.
