Whta is this ?
It is A 555 LED chaser board — a classic beginner PCB project.
Why I built this project ?
So this is one of the starter project in the stasis website, so when you went to this guide, I feel like that I want to make something without the SMD components only using the components that can be hand solder , so I went with this project and I learn a lot of things about the KiCad ,etc.

Questions
How big is the Blinky PCB?
It measures 43.4 × 29.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Blinky use?
22 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 Blinky KiCad files?
From the Sadrita404/Blinky repository on GitHub, at the commit this page was made from: the board is PCB/Blinky.kicad_pcb and its schematic PCB/Blinky.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Blinky design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
