From the project
Blinky in 3D!
I saw Zaurak's and Polyfloyd's LED cubes, and decided I wanted to make one too. This one is smaller with denser LEDs. (2mm pitch instead of 2.5mm)
The cube's faces are six LED panels from Aliexpress. Each panel has 64×64 RGB leds and is driven by the HUB75 protocol.
The chassis is a combination of 3D printed PLA, machine screws, and magnets. The electronics can be installed and removed without tools.

LED-Cube: common questions
What microcontroller does the LED-Cube use?
The LED-Cube is built around the Raspberry Pi, from the Raspberry Pi family.
How big is the LED-Cube PCB?
The LED-Cube measures 70 × 80 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the LED-Cube?
85 components, from 46 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the LED-Cube design files?
From the kbob/LED-Cube repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the LED-Cube design in my own project?
The repository has no license, so all rights stay with kbob. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the LED-Cube without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
