Questions
How big is the USB2514B PCB?
It measures 70 × 88 mm and has 4 copper layers, 0.46 mm thick.
What parts does the USB2514B use?
80 parts, built around the USBLC6-2P6, AP22615AWU, RT0402WRD0710KL and GXT155R61C105KE01D. 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 USB2514B KiCad files?
From the Ryanharma/USB2514B repository on GitHub, at the commit this page was made from: the board is USB2514B.kicad_pcb and its schematic USB2514B.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the USB2514B design in my own project?
Its repository states no licence, so its author keeps all rights: ask Ryanharma before reusing the design.
