Questions
How big is the Dualcomparator ls PCB?
It measures 47.8 × 45.5 mm and has 4 copper layers, 0.46 mm thick.
What parts does the Dualcomparator ls use?
28 parts. 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 Dualcomparator ls KiCad files?
From the daykin/levelshift-pcb repository on GitHub, at the commit this page was made from: the board is dualcomparator-ls.kicad_pcb and its schematic 12_to_-12.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dualcomparator ls design in my own project?
Its repository states no licence, so its author keeps all rights: ask daykin before reusing the design.
