June 20th: Wrote 1st revision of BOM (excluding power)

I first looked for a fitting switch chip that supported 2.5Gbit and was in stock.
After looking for a little bit I found this one

Following that, I read the datasheet and I discovered that 2 transceivers were needed for 2.5gbit

Because I want to keep some compatability with existing ethernet devices, I added 4 RJ-45 ports (two 2.5gbit ports, two 1gbit ports)

Some ethernet specs said I need to use magnetics so I also added them to the BOM (1 per RJ-45 Port, 4 total)

To connect the USB-Devices I added 3 USB-C Ports and USB to Ethernet Converters

Total time spent: 4h
