Questions
How big is the Timer PCB?
It measures 33 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Timer use?
8 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 Timer KiCad files?
From the Ethancao123/iRobotics-KiCAD-Tutorial repository on GitHub, at the commit this page was made from: the board is 555TimerDemo/timer.kicad_pcb and its schematic 555TimerDemo/timer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Timer design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
