Questions
How big is the Juggling machine pcb PCB?
It measures 97 × 95 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Juggling machine pcb use?
18 parts. 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 Juggling machine pcb KiCad files?
From the Learning-howto-Code/Juggling-Machine repository on GitHub, at the commit this page was made from: the board is juggling_machine_pcb/juggling_machine_pcb.kicad_pcb and its schematic juggling_machine_pcb/juggling_machine_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Juggling machine pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask Learning-howto-Code before reusing the design.
