Questions
How big is the Feuchtwerk PCB?
It measures 30 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Feuchtwerk use?
49 parts, built around the TJA1051-3M/TR, BMP280 and SFH3710. 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 Feuchtwerk KiCad files?
From the Bytewerk/feuchtwerk repository on GitHub, at the commit this page was made from: the board is feuchtwerk.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Feuchtwerk design in my own project?
Its repository states no licence, so its author keeps all rights: ask Bytewerk before reusing the design.
