The idea is to be able to move away the really big power supply and only have the new front panel visible. The UI is running on a Raspberry Pi with a 7" touch screen.

Questions
How big is the UsbKVM PCB?
It measures 85 × 35 mm and has 2 copper layers, 1.6 mm thick.
What parts does the UsbKVM use?
36 parts, built around the ATTINY13A-SU, CH334R, LM66200DRL and TS3USB30EDGSR-TP. 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 UsbKVM KiCad files?
From the YTvW/usbKVM-hardware repository on GitHub, at the commit this page was made from: the board is usbKVM/usbKVM.kicad_pcb and its schematic usbKVM/usbKVM.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the UsbKVM design in my own project?
Its repository states no licence, so its author keeps all rights: ask YTvW before reusing the design.
