Questions
How big is the Limiters PCB?
It measures 100 × 20 mm and has 4 copper layers, 1.59 mm thick.
What parts does the Limiters use?
143 parts, built around the LMV358 and MADL-011021-14150T. 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 Limiters KiCad files?
From the greatscottgadgets/misc repository on GitHub, at the commit this page was made from: the board is evaluation-boards/limiters/limiters.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Limiters design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
