Questions
How big is the Co2mon PCB?
It measures 58 × 41 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Co2mon use?
55 parts, built around the AP7313-33SRG, BSS138 and MICROSMD050F-2. 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 Co2mon KiCad files?
From the znuh/co2mon repository on GitHub, at the commit this page was made from: the board is hardware/kicad/co2mon.kicad_pcb and its schematic hardware/kicad/co2mon.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Co2mon design in my own project?
Its repository states no licence, so its author keeps all rights: ask znuh before reusing the design.
