Questions
How big is the WeatherStation v1.2 PCB?
It measures 36 × 49.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the WeatherStation v1.2 use?
17 parts, built around the ESP32-WROOM-32E, DHT22, AMS1117-3.3 and GUVA-S12SD. 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 WeatherStation v1.2 KiCad files?
From the ismangoman/Weather-station repository on GitHub, at the commit this page was made from: the board is Hardware/KiCAD/WeatherStation_v1.2.kicad_pcb and its schematic Hardware/KiCAD/WeatherStation_v1.2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the WeatherStation v1.2 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).
