Questions
How big is the BEN PCB?
It measures 44 × 91 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BEN use?
11 parts, built around the L135-A589003500000. 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 BEN KiCad files?
From the z0nathan/BasicEdgeNode repository on GitHub, at the commit this page was made from: the board is hardware/Electronics/BEN.kicad_pcb and its schematic hardware/Electronics/BEN.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BEN design in my own project?
Its repository publishes it under the CERN-OHL-W-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).
