Project description
[PROJECT INTRODUCTION & SYSTEM ARCHITECTURE] This project implements a compact embedded router architecture based on ESP32-S3 + Dual W5500 Ethernet controllers + 4G Cat.1 modem + Wi-Fi AP. It reproduces the structure of commercial SOHO routers, but at MCU level, providing: WAN/LAN separation Auto role-switching Ethernet (W5500 Card0) Dedicated LAN port (W5500 Card1) Wi-Fi AP in independent subnet (192.168.5.x) Dual Ethernet subnet (192.168.4.x) 4G modem as backup WAN (PPP) DHCP, NAT, bridge, and routing on ESP32-S3 Key Components ESP32-S3 — NAT, bridge, PPP, DHCP, AP W5500 × 2 — Dual-port…
