Questions
What parts does the Svetofor use?
47 parts, built around the ATMEGA8-16AU and AMS1117-5.0. 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 Svetofor KiCad files?
From the ilusder/traffic_lights repository on GitHub, at the commit this page was made from: the board is hw/svetofor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Svetofor design in my own project?
Its repository states no licence, so its author keeps all rights: ask ilusder before reusing the design.
