Questions
What parts does the Poc one use?
158 parts, built around the LMV321IDBVR, XYC-PT0805BC-L4-D, 74HC595D and 74HC138. 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 Poc one KiCad files?
From the ItsShadowCone/tmfl repository on GitHub, at the commit this page was made from: the board is hardware/poc-one/backup.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 Poc one design in my own project?
Its repository states no licence, so its author keeps all rights: ask ItsShadowCone before reusing the design.
