Questions
How big is the Housens L PCB?
It measures 50 × 50 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Housens L use?
53 parts, built around the MLPF-WB55-01E3, BME280, LM3670MF-1.8 and REG710NA-3/3K. 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 Housens L KiCad files?
From the passcod/Housens repository on GitHub, at the commit this page was made from: the board is Housens-L.kicad_pcb and its schematic Housens-L.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Housens L 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).
