Questions
How big is the OctalBusDisplay PCB?
It measures 100 × 51 mm and has 2 copper layers, 1.6 mm thick.
What parts does the OctalBusDisplay use?
18 parts, built around the 74AHC1G08GW and 86093967113745ELF. 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 OctalBusDisplay KiCad files?
From the TechPaula/DCJ11Hack- repository on GitHub, at the commit this page was made from: the board is Octal Display board/OctalBusDisplay/OctalBusDisplay.kicad_pcb and its schematic CPU Board/InvLED.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the OctalBusDisplay design in my own project?
Its repository states no licence, so its author keeps all rights: ask TechPaula before reusing the design.
