Questions
How big is the Comparator PCB?
It measures 97.8 × 20.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Comparator use?
20 parts, built around the CD4063BE. 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 Comparator KiCad files?
From the Trilobyte-CPU/8-bit-computer repository on GitHub, at the commit this page was made from: the board is PCBs/99_IN PROGRESS/IO-VGA-comparator/Comparator.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Comparator design in my own project?
Its repository states no licence, so its author keeps all rights: ask Trilobyte-CPU before reusing the design.
