PoE Switch Device

Project Overview:

I helped a company in Turkey as a free time activity.

This design was a compact, industrial-grade Ethernet node with integrated Power-over-Ethernet (PoE) and microcontroller-based management. It served as a connectivity interface for an IoT sensor platform. Not a technical challange, just have 10/100Mbit ethernet with PoE, isolated IoT input output, standart STM32 they used before, and old school buck converter

Technical Details

I designed it via 4 layer stackup:
