How big is the Monopulser PCB?
It measures 40 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Monopulser use?
19 parts, built around the 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 Monopulser KiCad files?
From the mrnuke/pcb-monopulser repository on GitHub, at the commit this page was made from: the board is monopulser.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Monopulser design in my own project?
Its repository states no licence, so its author keeps all rights: ask mrnuke before reusing the design.
