Questions
How big is the Sm4 PCB?
It measures 65 × 56 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Sm4 use?
142 parts, built around the TMC2226-SA-T, USBLC6-2SC6 and NDT2955. 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 Sm4 KiCad files?
From the matoushybl/sm4 repository on GitHub, at the commit this page was made from: the board is Hardware/rev2/sm4.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sm4 design in my own project?
Its repository states no licence, so its author keeps all rights: ask matoushybl before reusing the design.
