From the project
A DIY USB 2.0 Hub with 4 Type-A ports and a Type-C input, with a cute 3D printed scrappy cat case!! :3

Scrappy Tail connects to your device using USB Type-C (hence the cable making it look like a tail!) and gives you 4 additional USB Type-A ports. It uses the SL2.1A hub controller, so it uses USB 2.0 interface and thus speeds are limited to 480Mbps
PCB designed in KiCAD and CAD designed in OnShape.
