Questions
How big is the FujiNet 5.0 PCB?
It measures 132 × 162 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FujiNet 5.0 use?
50 parts, built around the 74LS245SC, ESP32-DEVKITC-VE, 74LS04PC and 74LS32SC. 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 FujiNet 5.0 KiCad files?
From the ThatOldNerd/FujiNet_20K repository on GitHub, at the commit this page was made from: the board is Hardware/FujiNet_5.0/FujiNet_5.0.kicad_pcb and its schematic Adapters/MSX Adapter/MSX Adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FujiNet 5.0 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
