Questions
How big is the Automatic street light PCB?
It measures 54 × 26 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Automatic street light use?
7 parts, built around the BC547. 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 Automatic street light KiCad files?
From the mil-aaa-n/Automatic-Light---PCB-Design repository on GitHub, at the commit this page was made from: the board is automatic_street_light.kicad_pcb and its schematic automatic_street_light.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Automatic street light design in my own project?
Its repository states no licence, so its author keeps all rights: ask mil-aaa-n before reusing the design.
