Questions
What parts does the Fpga usb use?
96 parts, built around the EP2C35F484I8, FT601Q-B-T, AMS1117-3.3 and PI5USB30213AXEAEX. 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 Fpga usb KiCad files?
From the tomverbeure/fpga_usb repository on GitHub, at the commit this page was made from: the board is fpga_usb/fpga_usb.kicad_pcb and its schematic fpga_usb/ep2c35_fpga.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Fpga usb design in my own project?
Its repository states no licence, so its author keeps all rights: ask tomverbeure before reusing the design.
