Questions
How big is the USB SPII2CK PCB?
It measures 50 × 31 mm and has 2 copper layers, 1.6 mm thick.
What parts does the USB SPII2CK use?
46 parts, built around the AT93C46DN-SH-T, FT2232HL, LP2985-33DBV and PRTR5V0U2X. 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 USB SPII2CK KiCad files?
From the mikef5410/USB_SPII2CK repository on GitHub, at the commit this page was made from: the board is USB_SPII2CK.kicad_pcb and its schematic USB_SPII2CK.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the USB SPII2CK design in my own project?
Its repository states no licence, so its author keeps all rights: ask mikef5410 before reusing the design.
