Questions
How big is the Pulser3 PCB?
It measures 41 × 41 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Pulser3 use?
72 parts, built around the RP2350A, BMP581, LM62460Q5RPHRQ1 and W25Q128JVSIQ. 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 Pulser3 KiCad files?
From the aaritkoundinya/Pulse repository on GitHub, at the commit this page was made from: the board is boards/r3/pulser3.kicad_pcb and its schematic boards/r2.1/pulser2.1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pulser3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask aaritkoundinya before reusing the design.
