Build Instructions
Verilog generation
The cube uses a Colorlight 5A-75B HUB75 controller board, revision v6.1. It has an ECP5-25 FPGA that's running a custom bitstream.
The RTL for that bitstream can be found in the ./rtl directory. It's written
with the SpinalHDL framework.

Questions
How big is the Cube2 PCB?
It measures 135 × 90 mm and has 2 copper layers, 1.69 mm thick.
What parts does the Cube2 use?
22 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Cube2 KiCad files?
From the tomverbeure/cube2 repository on GitHub, at the commit this page was made from: the board is pcb/cube2.kicad_pcb and its schematic libs/KiCad-RP-Pico/Test/Test.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cube2 design in my own project?
Its repository publishes it under the BSD-2-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
