M.2 2230 to Internal USB 2.0 Header
M.2 to USB V1.0 is an open-source printed circuit board by Supercookiegaming, from the Supercookiegaming/M.2-to-USB repository on GitHub. It is a 2-layer board of 22 × 30 mm with 30 parts on 71 nets, routed with 279 tracks and 96 vias.
It is built around the TPS61022RWUR and RH100-24.000-9-1015-EXT-TR. Its parts include 13 capacitors, 6 resistors, 4 ICs, 2 connectors and 1 inductor. It belongs with the computers and single-board computers boards of this library.
The M.2 to USB adapater uses the single USB 2.0 port on the A/E Key M.2 slot to make an USB front panel connector. The board uses the Microchip USB2422 2 port USB 2.0 hub IC. The hub allows 2 usb ports to be connected to the single port on the M.2 slot. This board is designed to handle 0.5 A per USB port, above that current the port will turn off. This was done because the M.2 slot can only provide 6.6 W. The 5V rail is made from the 3.3V found on the M.2 slot via a boost converter.
The board was designed to compatible with OSH Park's 2 layer 0.8mm thick PCB service.
The board is free to use for personal use only.

It measures 22 × 30 mm and has 2 copper layers, 0.93 mm thick.
30 parts, built around the TPS61022RWUR and RH100-24.000-9-1015-EXT-TR. 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 Supercookiegaming/M.2-to-USB repository on GitHub, at the commit this page was made from: the board is KiCad Files/M.2 to USB V1.0/M.2 to USB V1.0.kicad_pcb and its schematic KiCad Files/M.2 to USB V1.0/M.2 to USB V1.0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Supercookiegaming before reusing the design.
