Questions
How big is the LED PCB PCB?
It measures 73.5 × 75 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LED PCB 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 LED PCB KiCad files?
From the Abdulrahman0122/LED-PCB repository on GitHub, at the commit this page was made from: the board is led pcb.kicad_pcb and its schematic led pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LED PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask Abdulrahman0122 before reusing the design.
