Questions
How big is the 68k cpld devboard PCB?
It measures 82.3 × 56.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 68k cpld devboard use?
18 parts, built around the LM1117MP-3.3. 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 68k cpld devboard KiCad files?
From the dh219/68k_cpld_devboard repository on GitHub, at the commit this page was made from: the board is 68k_cpld_devboard.kicad_pcb and its schematic 68k_cpld_devboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 68k cpld devboard design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
