Questions
How big is the DustSensor PCB?
It measures 57.4 × 38.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DustSensor use?
24 parts, built around the ESP32-S3-WROOM-1-N8 and AMS1117-3.3. 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 DustSensor KiCad files?
From the pasquale-sergi/Dust-sensor-pcb repository on GitHub, at the commit this page was made from: the board is DustSensor.kicad_pcb and its schematic DustSensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DustSensor design in my own project?
Its repository states no licence, so its author keeps all rights: ask pasquale-sergi before reusing the design.
