Questions
How big is the MisterClippy PCB?
It measures 30.2 × 109.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MisterClippy use?
73 parts, built around the TL072, LM393 and BC547. 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 MisterClippy KiCad files?
From the rainerhassel/MisterClippy repository on GitHub, at the commit this page was made from: the board is PCB/misterclippy.kicad_pcb and its schematic PCB/clip_cv.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MisterClippy design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
