Questions
How big is the NO2 PCB?
It measures 33 × 28.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the NO2 use?
29 parts, built around the MICS-4514. 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 NO2 KiCad files?
From the r-map/rmap repository on GitHub, at the commit this page was made from: the board is kicad/stima_v2/breakout_board/NO2-CO/NO2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the NO2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask r-map before reusing the design.
