Questions
How big is the Usb switch PCB?
It measures 120 × 50 mm and has 6 copper layers, 0.85 mm thick.
What parts does the Usb switch use?
65 parts, built around the ESP32-S3-WROOM-1-N8R8, MAX20337AEFT+T, 74LVC1GU04DRL and DX07S024XJ1R1100. 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 Usb switch KiCad files?
From the cubicap/usb4-thing repository on GitHub, at the commit this page was made from: the board is usb-switch.kicad_pcb and its schematic control_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usb switch design in my own project?
Its repository states no licence, so its author keeps all rights: ask cubicap before reusing the design.
