Questions
How big is the DigiLight PCB?
It measures 95 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DigiLight use?
88 parts, built around the ATMEGA32-16AU, LM358, WS2811 and AMS1117-3.3. 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 DigiLight KiCad files?
From the mrKuzmich/DigiLightM_pcb repository on GitHub, at the commit this page was made from: the board is DigiLight.kicad_pcb and its schematic DigiLight.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DigiLight design in my own project?
Its repository states no licence, so its author keeps all rights: ask mrKuzmich before reusing the design.
