README
switchbox/README.mdSwitchbox
Mechanical switchbox to select one of two 6-pin inputs to be forwarded to one Analog RGBtoHDMI.
Note that only the 3 color signals and the csync is switched. The GND and +5V pins are always connected through. Therefore do not connect two cables that provide their +5V to the RGBtoHDMI at the same time, as these would then be shorted together, which could damage either or both of the connected machines.

Questions
How big is the Digitaladapter PCB?
It measures 33 × 12.7 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Digitaladapter use?
39 parts, built around the 74LVC1G17Z, 74LVC1G86Z and MIC5504-3.3YM5. 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 Digitaladapter KiCad files?
From the c0pperdragon/RGBtoHDMI_Accessories repository on GitHub, at the commit this page was made from: the board is digitaladapter/board/digitaladapter.kicad_pcb and its schematic digitaladapter/board/digitaladapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Digitaladapter design in my own project?
Its repository states no licence, so its author keeps all rights: ask c0pperdragon before reusing the design.
