Questions
How big is the FidgetSpinner PCB?
It measures 68.5 × 64 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FidgetSpinner use?
25 parts, built around the ATMEGA328P-AU and L78L05CZ. 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 FidgetSpinner KiCad files?
From the zosko/FidgetSpinner repository on GitHub, at the commit this page was made from: the board is hardware/FidgetSpinner.kicad_pcb and its schematic hardware/FidgetSpinner.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FidgetSpinner design in my own project?
Its repository states no licence, so its author keeps all rights: ask zosko before reusing the design.
