MARSUPIAL USB-PD + data hub
Marsupial (Motor And Regular Stuff USB PD Injector And Link) is a two port USB FS/HS hub which also is capable of injecting up to 60W per port (or 100W per port if I can implement USB PD EPR messages). The intended use for this is to be able to power and control motors over a single wire to both the motor and the PC, although it is fully USB PD compliant so you would be able to plug any other type of device into it. At the heart of the design is a programmable buck converter circuit which has a few predefined levels (5V, 9V, 12V, 15V, 20V, all at 3A, or 5A with EPR). In the future I would like to be able to implement Programmable Power Supply (PPS) functionality but at the moment this is out of scope of the project. It requires a large external 24V 120W power supply in order to power each port, and also features a daisy-chain connector on the back so that if you have multiple boards and a more powerful supply, you do not need to wire them all separately. The USB lines are brought out separately on an FFC connector so that the hub may be omitted and the signals manually handled off-board if desired.

Questions
How big is the Marsupial PCB?
It measures 53.1 × 98 mm and has 4 copper layers, 1.2 mm thick.
What parts does the Marsupial use?
208 parts, built around the SIC437BED, USB2412-DZK-TR, BL1551B and SRV05-4. 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 Marsupial KiCad files?
From the VIPQualityPost/marsupial repository on GitHub, at the commit this page was made from: the board is hardware/marsupial.kicad_pcb and its schematic hardware/USB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Marsupial design in my own project?
Its repository states no licence, so its author keeps all rights: ask VIPQualityPost before reusing the design.
