Questions
How big is the EnviroPuck PCB?
It measures 44 × 44 mm and has 4 copper layers, 1.6 mm thick.
What parts does the EnviroPuck use?
22 parts, built around the MDBT50Q-1MV2, BME680, GRM153C80G105ME15D and CL21A106KOQNNNE. 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 EnviroPuck KiCad files?
From the hlord2000/EnviroPuck repository on GitHub, at the commit this page was made from: the board is EnviroPuck.kicad_pcb and its schematic EnviroPuck.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EnviroPuck design in my own project?
Its repository publishes it under the CERN-OHL-P-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).
