My first pcb ever
ITS DONE AND IVE GOT IT WORKING WITH A BATTERY
AFTER MANY HOURS OF HARDWORK AND UNDERSTANDING THE PCB WORLD BETTER IVE FIINALLY BUJILT MY FIRST EVER PCB!!!
This was a long yet fun journey. From downloading KiCad to debugging errors after final pcb built. Everything is open-sourced so feel free to check out.
I used KiCad 8.0 instead of 10.0(latest as of now) because ver 8.0 had majority of new features yet simple rather than the latest one hope you enjoy!

Questions
How big is the My555 PCB?
It measures 97.1 × 93.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the My555 use?
19 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 My555 KiCad files?
From the iEarthEZ/555-LED-Chaser repository on GitHub, at the commit this page was made from: the board is my555.kicad_pcb and its schematic my555.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the My555 design in my own project?
Its repository states no licence, so its author keeps all rights: ask iEarthEZ before reusing the design.
