Questions
How big is the PulsePad PCB?
It measures 38.4 × 64.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PulsePad use?
15 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 PulsePad KiCad files?
From the sushan6/PulsePad1 repository on GitHub, at the commit this page was made from: the board is pcb/PulsePad.kicad_pcb and its schematic pcb/PulsePad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PulsePad design in my own project?
Its repository states no licence, so its author keeps all rights: ask sushan6 before reusing the design.
