Questions
What parts does the Dancing dots pcb use?
1,349 parts, built around the ICE40HX4K-TQ144, TLV75712PDBV, TLV75725PDBV and TLV75733PDRV. 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 Dancing dots pcb KiCad files?
From the softminus/dancing_dots repository on GitHub, at the commit this page was made from: the board is dancing_dots_pcb/dancing_dots_pcb.kicad_pcb and its schematic dancing_dots_pcb/control_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dancing dots pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask softminus before reusing the design.
