Questions
How big is the Noise measure QFN16(v0.2) PCB?
It measures 11.8 × 14.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Noise measure QFN16(v0.2) use?
19 parts, built around the OPA344PA. 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 Noise measure QFN16(v0.2) KiCad files?
From the Open-Air-Foundation/noise-module-pcb repository on GitHub, at the commit this page was made from: the board is noise_measure-QFN16(v0.2)/noise_measure-QFN16(v0.2).kicad_pcb and its schematic noise_measure(v0.1)/noise_measure(v0.1).kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Noise measure QFN16(v0.2) design in my own project?
Its repository states no licence, so its author keeps all rights: ask Open-Air-Foundation before reusing the design.
