Questions
How big is the Icosa code PCB?
It measures 91.2 × 91.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Icosa code use?
32 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 Icosa code KiCad files?
From the wldd22/icosa-code repository on GitHub, at the commit this page was made from: the board is pcb/icosa-code.kicad_pcb and its schematic pcb/icosa-code.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Icosa code design in my own project?
Its repository states no licence, so its author keeps all rights: ask wldd22 before reusing the design.
