From the project

This is a USB Hub that includes 2 USB A ports and 2 USB C ports. It is fully powered from the Upstream port and does not need any external power. All ports are 3.0!

So, I got tired of those cheap USB hubs that explode after a week lol. I decided to just make my own in KiCad. It’s got a mix of ports because, we’re all living in that annoying "half-USB-A, half-USB-C" era right now.

2x USB-A: For your mouse, keyboard, or that random flash drive you found.

2x USB-C: For the modern stuff (and because flipping the plug 3 times is annoying).
