Questions
How big is the Backplane v2 PCB?
It measures 440 × 205 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Backplane v2 use?
69 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 v2 KiCad files?
From the Nakazoto/FloatingPointSystems repository on GitHub, at the commit this page was made from: the board is FPS 100/Backplane_v2/Backplane_v2.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 v2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Nakazoto before reusing the design.
