Questions
How big is the LaserPointer PCB?
It measures 27.3 × 19.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LaserPointer use?
11 parts. 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 LaserPointer KiCad files?
From the ChenchuH/KiCad-Laser-Pointer-V1 repository on GitHub, at the commit this page was made from: the board is LaserPointer.kicad_pcb and its schematic LaserPointer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LaserPointer design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
