Questions
How big is the LaserPad PCB?
It measures 76.2 × 119.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LaserPad use?
85 parts, built around the 74AHCT1G125SE, PRTR5V0U2X, USBLC6-2SC6 and SK6812MINI-E. 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 LaserPad KiCad files?
From the LaserCrafter/LaserPad repository on GitHub, at the commit this page was made from: the board is LaserPad.kicad_pcb and its schematic LaserPad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LaserPad design in my own project?
Its repository states no licence, so its author keeps all rights: ask LaserCrafter before reusing the design.
