Questions
How big is the Noname PCB?
It measures 68 × 78 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Noname use?
109 parts, built around the ATTINY85-20SU, IR2101PBF, SI2308 and IRLR8726PBF. 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 Noname KiCad files?
From the nppc/DevBoards repository on GitHub, at the commit this page was made from: the board is AttinyDevBoard/noname.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Noname design in my own project?
Its repository states no licence, so its author keeps all rights: ask nppc before reusing the design.
