Questions
How big is the Smoke Sensor Module PCB?
It measures 41 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Smoke Sensor Module use?
19 parts, built around the LM393. 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 Smoke Sensor Module KiCad files?
From the tsanthosh1328-coder/pcb-designs repository on GitHub, at the commit this page was made from: the board is Smoke_Sensor_Module/Smoke_Sensor_Module.kicad_pcb and its schematic Accelerometer_and_Gryoscope_Sensor_Module/Accelerometer_and_Gryoscope_Sensor_Module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Smoke Sensor Module design in my own project?
Its repository states no licence, so its author keeps all rights: ask tsanthosh1328-coder before reusing the design.
