Questions
How big is the HoloCube PCB?
It measures 30 × 29 mm and has 4 copper layers, 1.6 mm thick.
What parts does the HoloCube use?
37 parts, built around the ESP32-PICO-D4, BH1750FVI-TR, MMBT3904 and WS2812B. 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 HoloCube KiCad files?
From the KisonHe/HoloCube-PCB repository on GitHub, at the commit this page was made from: the board is HoloCube/HoloCube.kicad_pcb and its schematic HoloCube/HoloCube.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HoloCube design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
