About the AVB Ethernet switch with CAN bus PCB

AVB Ethernet switch with CAN bus is an open source STM32 PCB design by guyg3333, published on GitHub. It is a 4-layer board measuring 137 × 55 mm, with 151 components from 28 distinct parts.

Its main chip is the STM32F765VITx, from the STM32 family. Other key parts include the KSZ8567STXI-TR, LINEAR_LDO and SN65HVD234. By type, the board carries 80 capacitors, 31 resistors, 16 connectors, 11 ICs, 5 inductors and 2 crystals.

From the project

Kicad Hardware project of in car network component to manage car traffic and bridge between different interfaces

This PCB was made As part of an Academic engineering final project, the idea behind it is to offer a method of reorganizing information traffic in autonomous vehicles,

The problem I wanted to solve is how to expand the current communication method to support Advanced Drive assist application.

The proposed solution is to build a network built from a combination of CAN bus and Ethernet interfaces, were Ethernet used as backbone.
