Questions
How big is the Light display sensor PCB?
It measures 26.9 × 49.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Light display sensor use?
21 parts, built around the MQ-4. 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 Light display sensor KiCad files?
From the vatral/nodemcu_light_sensor repository on GitHub, at the commit this page was made from: the board is board/light_display_sensor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Light display sensor design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
