Questions
How big is the 555 timer project PCB?
It measures 26 × 29 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 555 timer project use?
8 parts, built around the NE555D. 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 555 timer project KiCad files?
From the Tyrant0007/KiCad_Learning repository on GitHub, at the commit this page was made from: the board is 555_Timer_LED_Blinker_PCB/Project_Files/555_timer_project.kicad_pcb and its schematic 555_Timer_LED_Blinker_PCB/Project_Files/555_timer_project.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 555 timer project design in my own project?
Its repository states no licence, so its author keeps all rights: ask Tyrant0007 before reusing the design.
