KiCad overspec usb hub
Usb2517 pinlevel is an open-source printed circuit board by freeprochat, from the freeprochat/USB-hub repository on GitHub. It is a 4-layer board of 170 × 115 mm with 19 parts on 42 nets, routed with 39 tracks and 0 vias.
It is built around the AP22653W6 and AP2112K-3.3. Its parts include 10 ICs and 9 connectors.
This package contains a normal legacy KiCad schematic with a custom cache library, a 64-pin USB2517 symbol, explicit pin-to-net connectivity matrix, a four-layer PCB with pads, named nets, differential routes, high-current power routes and GND/5V zones. KiCad 6-9 can open and convert the legacy .sch to modern .kicad_sch.
Important: The PCB is a complete connected engineering draft, not a production release. The Molex and TI footprints are dimensionally tagged but are not authenticated manufacturer ECAD downloads. Run ERC/DRC after conversion on a workstation with KiCad installed, confirm all footprint land patterns from the current drawings, tune USB impedance to the fab stackup, and perform power/thermal/USB compliance testing.

It measures 170 × 115 mm and has 4 copper layers, 1.6 mm thick.
19 parts, built around the AP22653W6 and AP2112K-3.3. 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.
From the freeprochat/USB-hub repository on GitHub, at the commit this page was made from: the board is usb2517_pinlevel_complete_kicad/usb2517_pinlevel.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask freeprochat before reusing the design.
