From the project
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.

Ledcube: common questions
What microcontroller does the Ledcube use?
The Ledcube is built around the Raspberry Pi, from the Raspberry Pi family.
How big is the Ledcube PCB?
The Ledcube measures 70 × 80 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Ledcube?
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 Ledcube design files?
From the philipwig/ledcube repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Ledcube design in my own project?
The repository has no license, so all rights stay with philipwig. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Ledcube 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.
