Questions
How big is the Single board PCB?
It measures 160 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Single board use?
87 parts, built around the MC68030FE16C, 74HC253D, 74HC05D and 74HC08D. 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 Single board KiCad files?
From the PrinceYadav78/Single-Board-Computer repository on GitHub, at the commit this page was made from: the board is PCB/Single_board.kicad_pcb and its schematic PCB/Bus.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Single 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).
