Questions
How big is the Traffic light PCB?
It measures 35 × 130 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Traffic light use?
53 parts, built around the ESP-12F, AMS1117-3.3 and BS170. 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 Traffic light KiCad files?
From the iley/traffic-light repository on GitHub, at the commit this page was made from: the board is pcb/traffic_light.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Traffic light design in my own project?
Its repository states no licence, so its author keeps all rights: ask iley before reusing the design.
