Questions
How big is the Pulse 4k PCB?
It measures 61 × 43.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pulse 4k use?
39 parts, built around the ATMEGA32U4-AU and WS2812B. 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 Pulse 4k KiCad files?
From the Maxr1998/Pulse_4k repository on GitHub, at the commit this page was made from: the board is pcb/pcb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pulse 4k design in my own project?
Its repository states no licence, so its author keeps all rights: ask Maxr1998 before reusing the design.
