Questions
How big is the Transparent one PCB?
It measures 275 × 200 mm and has 2 copper layers, 0.24 mm thick.
What parts does the Transparent one use?
81 parts, built around the 74HC595D, 74HC138 and ABM8-272-T3. 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 Transparent one KiCad files?
From the ItsShadowCone/tmfl repository on GitHub, at the commit this page was made from: the board is hardware/transparent-one/transparent-one.kicad_pcb and its schematic hardware/frontcover/frontcover.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Transparent one design in my own project?
Its repository states no licence, so its author keeps all rights: ask ItsShadowCone before reusing the design.
