Questions
How big is the Arithmetic PCB?
It measures 49.5 × 48.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Arithmetic use?
70 parts, built around the LM317. 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 Arithmetic KiCad files?
From the bodokaiser/position-sensitive-detector repository on GitHub, at the commit this page was made from: the board is kicad/arithmetic.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Arithmetic design in my own project?
Its repository states no licence, so its author keeps all rights: ask bodokaiser before reusing the design.
