Questions

How big is the Mini Module PCB?

It measures 38 × 33.2 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Mini Module use?

29 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 Mini Module KiCad files?

From the sullyjason/interactiles repository on GitHub, at the commit this page was made from: the board is Button_Modules/Mini/Mini_Module/Mini_Module.kicad_pcb and its schematic 2x2 Interactiles/PCB/Controller PCB/RGB 2x2 with WS2811.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Mini Module design in my own project?

Its repository states no licence, so its author keeps all rights: ask sullyjason before reusing the design.
