Other key parts include the CH334F and USBLC6-2SC6. By type, the board carries 8 capacitors, 2 ICs, 2 connectors, 1 crystal and 1 resistor.

It belongs with the usb & debug tools designs in this gallery.

From the project

Framework Expansion Card that includes a USB hub to hide a bare dongle inside and still have a USB-A port externally

Want to use a Logitech Unifying Dongle (or similar) without having a dongle permanently sticking out and giving up on a precious expansion card slot?

Simply (permanently) mount the dongle inside the card and still have an USB A port available!

There even is room and solder pads for 1-2 additional dongles. Your imagination (and physics) are the only limits!

See also the thread on Mastodon about the build process etc.
