BOM
Cost
BOM (1 board + case): LCSC[6.92 USD + 3 USD handling + 9.38 USD shipping = 19.3 USD] + AliExpress[4.53 USD] = 23.83 USD
PCB: 2 USD + 3.3 USD shipping = 5.3 USD
Total: 29.13 USD (1 board + case)
Assembly
Prerequisites: soldered PCB and printed case (PRINT THE CASE WITH +1-2% SCALE FOR TOLERANCES)
- Mark out the dimensions of the acrylic window and use a scoring tool to cut it
- From the sides, glue the acrylic window into the top case
- Wait for glue to set
- Place completed PCB into bottom case (optionally, affix it with double sided tape, but it should be held in place by friction anyway
- Glue the top half onto bottom half (I tried, with this kind of size its not very feasible to use screws or anything)

Questions
How big is the YetAnotherUSBHub PCB?
It measures 77.6 × 32.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the YetAnotherUSBHub use?
29 parts, built around the GL823K-HCY04, TPD2E2U06DCK and TPD6F003DQD. 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 YetAnotherUSBHub KiCad files?
From the 0x62b/YetAnotherUSBHub repository on GitHub, at the commit this page was made from: the board is pcb/YetAnotherUSBHub.kicad_pcb and its schematic pcb/YetAnotherUSBHub.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the YetAnotherUSBHub design in my own project?
Its repository states no licence, so its author keeps all rights: ask 0x62b before reusing the design.
