Questions
How big is the Ematch2 PCB?
It measures 80 × 43 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ematch2 use?
46 parts, built around the DMG3402L and DMG3401LSN. 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 Ematch2 KiCad files?
From the albachten/ematch2 repository on GitHub, at the commit this page was made from: the board is Ematch2.kicad_pcb and its schematic Ematch2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ematch2 design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
