Questions
How big is the Windsensor PCB?
It measures 70 × 70 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Windsensor use?
128 parts, built around the ESP32-S3-WROOM-1-N8, DPS368, BMM350 and TF-012. 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 Windsensor KiCad files?
From the kristofkatzenberger/windsensor repository on GitHub, at the commit this page was made from: the board is ECAD/windsensor.kicad_pcb and its schematic ECAD/compass.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Windsensor 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).
