Questions
How big is the Kickstart switcher PCB?
It measures 20.3 × 31.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Kickstart switcher use?
15 parts, built around the 74HC14 and 74HC74D. 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 Kickstart switcher KiCad files?
From the keirf/pcb-projects repository on GitHub, at the commit this page was made from: the board is kickstart-switcher/v1/kickstart-switcher.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kickstart switcher design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
