Questions
How big is the Ns32k PCB?
It measures 145.5 × 89.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Ns32k use?
138 parts, built around the 74AHC245D, CP2102N-EK, 74AHC1GU04SE and 74AHC373D. 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 Ns32k KiCad files?
From the bson/ns32k repository on GitHub, at the commit this page was made from: the board is ns32k.kicad_pcb and its schematic ethernet.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ns32k design in my own project?
Its repository states no licence, so its author keeps all rights: ask bson before reusing the design.
