Questions
How big is the LaserProjector PCB?
It measures 63.5 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LaserProjector use?
67 parts, built around the ESP32-WROOM-32, DAC8562EP, AP1117DG and LM7809CT. 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 LaserProjector KiCad files?
From the yaqwsx/LaserProjector repository on GitHub, at the commit this page was made from: the board is hw/mainBoard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LaserProjector 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).
