Questions
How big is the Frameboard usb PCB?
It measures 59.2 × 34 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Frameboard usb use?
40 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 Frameboard usb KiCad files?
From the xjanu/frameboard-usb repository on GitHub, at the commit this page was made from: the board is board/frameboard-usb.kicad_pcb and its schematic board/frameboard-usb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Frameboard usb design in my own project?
Its repository states no licence, so its author keeps all rights: ask xjanu before reusing the design.
