Questions
How big is the AirMon PCB?
It measures 66 × 99.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AirMon use?
130 parts, built around the CH340C, ESP32-WROOM-32, PMS7003M and LMR14010ADDCR. 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 AirMon KiCad files?
From the SG-O/airMon repository on GitHub, at the commit this page was made from: the board is airMon.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the AirMon design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
