Questions
How big is the Atmosensor kicad PCB?
It measures 46 × 36 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Atmosensor kicad use?
31 parts, built around the AMS1117-3.3 and USBLC6-2SC6. 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 Atmosensor kicad KiCad files?
From the ssnover/atmosensor repository on GitHub, at the commit this page was made from: the board is atmosensor-kicad/atmosensor-kicad.kicad_pcb and its schematic atmosensor-kicad/atmosensor-kicad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Atmosensor kicad design in my own project?
Its repository states no licence, so its author keeps all rights: ask ssnover before reusing the design.
