Questions
How big is the Weather PCB?
It measures 70 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Weather use?
47 parts, built around the XL1509-5.0E1, CJ431 and BAV99. 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 Weather KiCad files?
From the mdarty/WeatherStation repository on GitHub, at the commit this page was made from: the board is Weather/Weather.kicad_pcb and its schematic Weather/Audio.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Weather 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).
