Questions
How big is the Emu Board PCB?
It measures 323.8 × 117.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Emu Board use?
156 parts. 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 Emu Board KiCad files?
From the Emmanuel-Roy/Emu-Board repository on GitHub, at the commit this page was made from: the board is Emu_Board/Emu_Board.kicad_pcb and its schematic Emu_Board/Emu_Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Emu Board 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).
