Questions
How big is the LED chaser PCB?
It measures 76.2 × 41 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LED chaser use?
20 parts, built around the CD4017BE and 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 LED chaser KiCad files?
From the emnguynhoccode/KiCad_LED_Chaser_202514301 repository on GitHub, at the commit this page was made from: the board is LED_chaser.kicad_pcb and its schematic LED_chaser.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LED chaser design in my own project?
Its repository states no licence, so its author keeps all rights: ask emnguynhoccode before reusing the design.
