Questions
How big is the OSM env01 PCB?
It measures 160 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the OSM env01 use?
243 parts, built around the CP2102N-A01-GQFN24, ESP-WROOM-32D, LMV324 and MIC2288YD5-TR. 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 OSM env01 KiCad files?
From the devtank-ltd/kicad_osm_env01 repository on GitHub, at the commit this page was made from: the board is kicad_osm_env01/OSM_env01.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the OSM env01 design in my own project?
Its repository states no licence, so its author keeps all rights: ask devtank-ltd before reusing the design.
