Questions
How big is the Swc PCB?
It measures 43.5 × 45.7 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Swc use?
64 parts, built around the TJA1051T/3/1, XC6206P332MR, FTSH-107-01-F-DV-K and PESD1CAN. 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 Swc KiCad files?
From the mck1117/swc repository on GitHub, at the commit this page was made from: the board is hardware/swc/swc.kicad_pcb and its schematic hardware/slipring/swc_slipring/swc_slipring.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Swc design in my own project?
Its repository states no licence, so its author keeps all rights: ask mck1117 before reusing the design.
