Questions
How big is the Backplane PCB?
It measures 397.9 × 240.4 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Backplane use?
27 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 Backplane KiCad files?
From the Nakazoto/FloatingPointSystems repository on GitHub, at the commit this page was made from: the board is FPS 100/Backplane/Backplane.kicad_pcb and its schematic FPS 100/!Old/Reverse Engineer/Backplane/Backplane.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Backplane design in my own project?
Its repository states no licence, so its author keeps all rights: ask Nakazoto before reusing the design.
