Questions
How big is the Hub usb sd PCB?
It measures 50 × 50 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Hub usb sd use?
65 parts, built around the AT24C04N, TPS2052CDGN, BGX50AE6327 and SS34. 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 Hub usb sd KiCad files?
From the dougsthenri/hub_usb_sd repository on GitHub, at the commit this page was made from: the board is hub_usb_sd.kicad_pcb and its schematic hub_usb_sd.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hub usb sd design in my own project?
Its repository states no licence, so its author keeps all rights: ask dougsthenri before reusing the design.
