Questions
How big is the EfxSelector v2 PCB?
It measures 257 × 41 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EfxSelector v2 use?
48 parts, built around the IR204-A-L and EC2-4.5NU. 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 EfxSelector v2 KiCad files?
From the n8b5150/EfxSelector repository on GitHub, at the commit this page was made from: the board is EfxSelector_v2.kicad_pcb and its schematic EfxSelector_v2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EfxSelector v2 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).
