Questions
How big is the PETRAMROM PCB?
It measures 87 × 62.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PETRAMROM use?
21 parts, built around the 74LS245SC. 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 PETRAMROM KiCad files?
From the rfalize/PETRAMROM repository on GitHub, at the commit this page was made from: the board is KiCAD/PETRAMROM.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PETRAMROM design in my own project?
Its repository states no licence, so its author keeps all rights: ask rfalize before reusing the design.
