Questions
How big is the 486 Board PCB?
It measures 233.4 × 100 mm and has 4 copper layers, 4.69 mm thick.
What parts does the 486 Board use?
119 parts, built around the 74LVC1GU04DRL. 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 486 Board KiCad files?
From the FoxCutter/486Dev repository on GitHub, at the commit this page was made from: the board is 486 Board/486 Board.kicad_pcb and its schematic 486 Board/486 Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 486 Board design in my own project?
Its repository publishes it under the BSD-3-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
