Questions
What parts does the Modularized use?
200 parts, built around the NJM4558, LA6358N-E, 2SC1740S-TA and 1N4148W. 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 Modularized KiCad files?
From the Jeff-Russ/Casio-HT-700-mods repository on GitHub, at the commit this page was made from: the board is Modularized/Modularized.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Modularized design in my own project?
Its repository states no licence, so its author keeps all rights: ask Jeff-Russ before reusing the design.
