Questions
How big is the Hub75 S3 PCB?
It measures 50 × 48 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hub75 S3 use?
15 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 Hub75 S3 KiCad files?
From the MoonModules/Hardware repository on GitHub, at the commit this page was made from: the board is MOONHUB75/project/hub75_S3.kicad_pcb and its schematic 74AHCT125_Shifter/project/sn74ahct125_normal.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hub75 S3 design in my own project?
Its repository publishes it under the CERN-OHL-S-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).
