Questions
How big is the Anemometer board PCB?
It measures 48.9 × 33.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Anemometer board use?
16 parts, built around the QMC5883L. 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 Anemometer board KiCad files?
From the 21km43/anemometer_board repository on GitHub, at the commit this page was made from: the board is anemometer_board.kicad_pcb and its schematic anemometer_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Anemometer board design in my own project?
Its repository states no licence, so its author keeps all rights: ask 21km43 before reusing the design.
