Questions
How big is the Led flasher PCB?
It measures 18.5 × 18.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Led flasher use?
16 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 Led flasher KiCad files?
From the eys123/eclectronics-led-flasher repository on GitHub, at the commit this page was made from: the board is led_flasher/led_flasher.kicad_pcb and its schematic led_flasher/led_flasher.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Led flasher design in my own project?
Its repository states no licence, so its author keeps all rights: ask eys123 before reusing the design.
