Questions
How big is the Laser control PCB?
It measures 40.6 × 57.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Laser control use?
20 parts, built around the H11L1, 74HCT02D and BC846A. 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 control KiCad files?
From the begemotv2718/laser_control repository on GitHub, at the commit this page was made from: the board is laser_control.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Laser control design in my own project?
Its repository states no licence, so its author keeps all rights: ask begemotv2718 before reusing the design.
