Questions
How big is the Nkdevboard PCB?
It measures 52 × 34 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Nkdevboard use?
30 parts, built around the ATSAMD21G18A-AU, AP2112K-3.3 and USBLC6-2SC6. 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 Nkdevboard KiCad files?
From the Nitheesh-226/kicad-projects repository on GitHub, at the commit this page was made from: the board is nkdevboard.kicad_pcb and its schematic nkdevboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nkdevboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask Nitheesh-226 before reusing the design.
