Questions
How big is the Kwantizer PCB?
It measures 30 × 128.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Kwantizer use?
32 parts, built around the ADS1115IDGS, LM317 and BAT41. 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 Kwantizer KiCad files?
From the benjiaomodular/Kwantizer repository on GitHub, at the commit this page was made from: the board is KiCad/Kwantizer/Kwantizer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kwantizer design in my own project?
Its repository states no licence, so its author keeps all rights: ask benjiaomodular before reusing the design.
