Questions
How big is the Ez usb dev board PCB?
It measures 50 × 50 mm and has 8 copper layers, 1.62 mm thick.
What parts does the Ez usb dev board use?
287 parts, built around the CYUSB3014-BZXC, W25X20CLSNIG, 93LC56BT-I/OT and FT2232HL. 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 Ez usb dev board KiCad files?
From the jkmunson/EENG490 repository on GitHub, at the commit this page was made from: the board is ez_usb_dev_board/ez_usb_dev_board.kicad_pcb and its schematic analog_tile/analog_tile/analog_tile.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ez usb dev board design in my own project?
Its repository states no licence, so its author keeps all rights: ask jkmunson before reusing the design.
