Questions
How big is the Nack PCB?
It measures 247.7 × 84 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Nack use?
278 parts, built around the LL4148, WS2812C-2020-V1, TPD4E02B04DQAR and KRC106S. 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 Nack KiCad files?
From the farfalleflickan/nack repository on GitHub, at the commit this page was made from: the board is nack_v1/hardware/nack.kicad_pcb and its schematic nack_v2/hardware/nack.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nack design in my own project?
Its repository publishes it under the AGPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
