Questions
How big is the AirMonitor PCB?
It measures 49 × 50.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AirMonitor use?
60 parts, built around the ESP32-C3-MINI-1, PMS7003M, BMP581 and SGP41-D-R4. 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 AirMonitor KiCad files?
From the JJendryka/AirMonitor repository on GitHub, at the commit this page was made from: the board is AirMonitor.kicad_pcb and its schematic AirMonitor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AirMonitor design in my own project?
Its repository states no licence, so its author keeps all rights: ask JJendryka before reusing the design.
