README
README.mdUSB controlled HDMI Switch
I couldn't find one of these easily, so I decided to make one myself.
This uses a PI3HDX621 3.4Gbps HDMI1.4b Active 2:1 Switch with ARC and Fast Switching paired with a SAMD21 microcontroller (because I had some in stock).
The firmware is implemented with my library libsam.
Untested things - the switch IC supports ARC, but I didn't test that yet because I don't have anything handy that supports it.

Questions
How big is the Hdmi switch PCB?
It measures 60 × 45 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Hdmi switch use?
65 parts, built around the 74LVC1G07, 74LVC1G125, TXS0102DCU and AMS1117-3.3. 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 Hdmi switch KiCad files?
From the Stary2001/hdmi-switch repository on GitHub, at the commit this page was made from: the board is hardware/v0.1/hdmi-switch.kicad_pcb and its schematic hardware/v0.1/hdmi-switch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hdmi switch design in my own project?
Its repository states no licence, so its author keeps all rights: ask Stary2001 before reusing the design.
