# skibidi-birthday

Happy birthday [Kai](https://github.com/KaiPereira)!! I wanted to put some FPGA footprint stuff but its too advanced for me lol. Hope you enjoy this card gift.

This is a USB 2.0 Hub, it doesn't need to have a case because the pcb itself is a birthday card, having a case would obviously hides the decorations and art on the pcb so it makes sense to not have a case designed.
