Questions
How big is the Ds1 PCB?
It measures 52.3 × 84.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ds1 use?
88 parts, built around the OPA604AU, 1N34A and KSC945YTA. 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 Ds1 KiCad files?
From the gzramon/Ds1 repository on GitHub, at the commit this page was made from: the board is ds.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ds1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask gzramon before reusing the design.
