Questions
How big is the Laser PCB?
It measures 74.9 × 31.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Laser use?
68 parts, built around the NE555D and PMBT2222A. 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 Laser KiCad files?
From the wryan67/5x7laser repository on GitHub, at the commit this page was made from: the board is schematic/kicad/main/laser.kicad_pcb and its schematic schematic/kicad/barrel/barrel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Laser 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).
