Questions
How big is the Arcus PCB?
It measures 110 × 52 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Arcus use?
72 parts, built around the RP2040, W25Q128JVSIQ, AFC07-S24FCA-00 and AMS1117-3.3. 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 Arcus KiCad files?
From the MeghanaM4/arcus repository on GitHub, at the commit this page was made from: the board is arcus.kicad_pcb and its schematic arcus.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Arcus design in my own project?
Its repository states no licence, so its author keeps all rights: ask MeghanaM4 before reusing the design.
