Questions
How big is the Cube display PCB?
It measures 85 × 85 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cube display use?
73 parts, built around the ESP32-S3-WROOM-1-N8, MAX98357AETE+T, LSM6DS3 and MSS12C02LS-BB2.0. 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 Cube display KiCad files?
From the atomic14/cube-display repository on GitHub, at the commit this page was made from: the board is main-board/main-board.kicad_pcb and its schematic display-board/display-board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cube display design in my own project?
Its repository states no licence, so its author keeps all rights: ask atomic14 before reusing the design.
