Questions
How big is the Arcnet PCB?
It measures 99.7 × 50.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Arcnet use?
29 parts, built around the COM20020I-HT, 74HCT138D and SD05. 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 Arcnet KiCad files?
From the tpycio/RCNetwork repository on GitHub, at the commit this page was made from: the board is Arcnet.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Arcnet design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
