Questions
How big is the BLINKING LED USING 555 PCB?
It measures 40 × 24.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BLINKING LED USING 555 use?
15 parts. 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 BLINKING LED USING 555 KiCad files?
From the rajeev2705/PROJECTS repository on GitHub, at the commit this page was made from: the board is Kicad Projects/555_BLINKING_LED/BLINKING_LED_USING_555/BLINKING_LED_USING_555.kicad_pcb and its schematic Kicad Projects/3.3V DC Buck Boost Converter/3.3V Buck Boost Converter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BLINKING LED USING 555 design in my own project?
Its repository states no licence, so its author keeps all rights: ask rajeev2705 before reusing the design.
