Questions
How big is the Nyx2b PCB?
It measures 51 × 21 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Nyx2b use?
54 parts, built around the W25Q128JVSIQ, ME6211C33M5G-N, USBLC6-2SC6 and USB4215-03-A. 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 Nyx2b KiCad files?
From the rh1tech/nyx repository on GitHub, at the commit this page was made from: the board is hardware/nyx2b/nyx2b.kicad_pcb and its schematic hardware/nyx1/nyx1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nyx2b design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
