Questions
How big is the SimpleDiodeSelector PCB?
It measures 35.6 × 55.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SimpleDiodeSelector use?
37 parts, built around the BAT41, BAT46 and BAV21. 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 SimpleDiodeSelector KiCad files?
From the hinds44/SimpleDiodeSelector repository on GitHub, at the commit this page was made from: the board is SimpleDiodeSelector/SimpleDiodeSelector.kicad_pcb and its schematic SimpleDiodeSelector/SimpleDiodeSelector.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SimpleDiodeSelector design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
