Questions
How big is the DZ44 PCB?
It measures 107.2 × 130 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DZ44 use?
110 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 DZ44 KiCad files?
From the Nakazoto/Data620 repository on GitHub, at the commit this page was made from: the board is Schematics/Reverse Engineering/DZ44/DZ44.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the DZ44 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Nakazoto before reusing the design.
