Questions
What parts does the Reg use?
21 parts, built around the 74LS377PC and SN74LVC1G14DBV. 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 Reg KiCad files?
From the magik6k/breadv repository on GitHub, at the commit this page was made from: the board is pcbs/reg/reg.kicad_pcb and its schematic pcbs/8view-out/8view-out.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Reg design in my own project?
Its repository states no licence, so its author keeps all rights: ask magik6k before reusing the design.
