Questions
How big is the Us extender PCB?
It measures 135.2 × 25 mm and has 4 copper layers, 4.69 mm thick.
What parts does the Us extender use?
108 parts, built around the SY6280AAAC, TUSB8042AIRGCT, AMS1117-3.3 and GSB412137CHR. 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 Us extender KiCad files?
From the R-Mutura/usb_extender repository on GitHub, at the commit this page was made from: the board is src/us extender/us extender.kicad_pcb and its schematic src/us extender/3V3 ams1117 1A.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Us extender design in my own project?
Its repository states no licence, so its author keeps all rights: ask R-Mutura before reusing the design.
