Questions
What parts does the Russell use?
31 parts, built around the BME280 and CN3158. 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 Russell KiCad files?
From the meshmy/russell repository on GitHub, at the commit this page was made from: the board is russell.kicad_pcb and its schematic russell.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Russell design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
