Questions
How big is the Noise measurement PCB?
It measures 12.4 × 23.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Noise measurement use?
21 parts, built around the MSP430G2210ID and 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 measurement KiCad files?
From the tle-airgradient/Noise-Measurement-pcb repository on GitHub, at the commit this page was made from: the board is noise_measurement/noise_measurement.kicad_pcb and its schematic noise_measurement/noise_measurement.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Noise measurement design in my own project?
Its repository states no licence, so its author keeps all rights: ask tle-airgradient before reusing the design.
