Overview

This project is an automotive oriented hub. It has an upstream USB-C with USB 3.2 Gen 2 characteristics coupled with a hub chip that outputs various GPIO functionality, from which UART is used for RS485, alongside two USB 2.0 and one USB 3.2 Gen 2 connectors.

It also houses a 10/100/1000 ethernet that works off of a USB to Ethernet converter IC.

The power input is 10-24V, which is regulated down to 5V/1.2V/3.3V.

The board uses a 6 layer stackup from Aisler.
