Serial controlled USB Switch
I was tired of pressing a button to switch a usb device between two computers, and I noticed industrial solutions are there but they cost A LOT. so I tried to design my own usb switch with serial communication, so I can build automations with it and I can switch the ports using a small utility program running on my pc.
As a bonus, it also exposes a UART header to cascade control another device with a single USB C port.
The real challenge here was, to route differential tracks with impedence matching.
