Questions
How big is the EightZero PCB?
It measures 155.6 × 90.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EightZero use?
29 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 EightZero KiCad files?
From the Noah1989/EightZero repository on GitHub, at the commit this page was made from: the board is pcb/eightzero.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the EightZero design in my own project?
Its repository states no licence, so its author keeps all rights: ask Noah1989 before reusing the design.
