Questions
How big is the 555-LED Chaser PCB?
It measures 86 × 86 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 555-LED Chaser use?
18 parts, built around the NE555P. 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 555-LED Chaser KiCad files?
From the avycado13/555-LED-Chaser repository on GitHub, at the commit this page was made from: the board is 555-LED-Chaser.kicad_pcb and its schematic 555-LED-Chaser.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 555-LED Chaser design in my own project?
Its repository states no licence, so its author keeps all rights: ask avycado13 before reusing the design.
