Questions
How big is the WorldCubeProtoV1 PCB?
It measures 95.2 × 112.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the WorldCubeProtoV1 use?
125 parts, built around the PAM8406DR, TCA9548ARGER, TLV61047DDC and PCM1681PWP. 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 WorldCubeProtoV1 KiCad files?
From the shBLOCK/WorldCube repository on GitHub, at the commit this page was made from: the board is pcb/WorldCubeProtoV1/WorldCubeProtoV1.kicad_pcb and its schematic pcb/WorldCubeProtoV1/WorldCubeProtoV1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the WorldCubeProtoV1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask shBLOCK before reusing the design.
