Questions
How big is the Z80DevBoard PCB?
It measures 101.6 × 83.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Z80DevBoard use?
39 parts, built around the 74AC00, 74AC04PC, 74AC08PC and 74AC138SC. 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 Z80DevBoard KiCad files?
From the dbuchwald/Z80DevBoard repository on GitHub, at the commit this page was made from: the board is Schematic/Z80_Dev_Board/Z80_Dev_Board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Z80DevBoard 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).
