Questions
How big is the Luftmeter PCB?
It measures 101.1 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Luftmeter use?
85 parts, built around the LPV521MG, CP2102N-A01-GQFN24, ESP32-WROOM-32 and ADS1119IPW. 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 Luftmeter KiCad files?
From the stustanet/Luftmeter repository on GitHub, at the commit this page was made from: the board is PCB/luftmeter.kicad_pcb and its schematic PCB/luftmeter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Luftmeter design in my own project?
Its repository states no licence, so its author keeps all rights: ask stustanet before reusing the design.
