Questions
How big is the SixPad PCB?
It measures 77.2 × 60.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SixPad use?
19 parts, built around the 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 SixPad KiCad files?
From the Dreamer-Cloud-blip/HackPad repository on GitHub, at the commit this page was made from: the board is PCB/SixPad.kicad_pcb and its schematic PCB/SixPad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SixPad design in my own project?
Its repository states no licence, so its author keeps all rights: ask Dreamer-Cloud-blip before reusing the design.
