Questions
How big is the Meteostation PCB?
It measures 87.9 × 71.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Meteostation use?
175 parts, built around the ESP8266EX, SX1278IMLTRT, AT25SF081-SHD-T and DHT11. 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 Meteostation KiCad files?
From the aleksul/WeatherStation repository on GitHub, at the commit this page was made from: the board is hardware/meteostation.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Meteostation 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).
