Questions
How big is the Netholi PCB?
It measures 80.2 × 72.3 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Netholi use?
212 parts, built around the SY8008CAAC, AXP209 and DB15. 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 Netholi KiCad files?
From the expeyes/expeyes-programs repository on GitHub, at the commit this page was made from: the board is SBC/netholi/netholi.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Netholi design in my own project?
Its repository states no licence, so its author keeps all rights: ask expeyes before reusing the design.
