Questions
How big is the Skywatch PCB?
It measures 233.7 × 91.5 mm and has 2 copper layers, 1.2 mm thick.
What parts does the Skywatch use?
133 parts, built around the RP2040, GD25Q80CEIGR, XC6210B332MR-G and 1N4148W. 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 Skywatch KiCad files?
From the ozkan/skywatch repository on GitHub, at the commit this page was made from: the board is Hardware/skywatch.kicad_pcb and its schematic Hardware/skywatch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Skywatch design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
