ESP32 LAN Module

ESP32 LAN Module

This project adds wired connectivity and versatile I/O options to the Modular ESP32 Case system. The ESP32 LAN Module integrates seamlessly with the base enclosure and provides dual RJ45 ports that can be used for Ethernet networking, direct sensor connections, or custom communication links.

Designed with flexibility in mind, the LAN ports are not limited to networking only. They can be repurposed for structured cabling to sensors, industrial-style wiring, or point-to-point connections—making this module ideal for smart home installations, lab setups, and embedded projects.

Features

• Modular plug-in design for the Modular ESP32 Case
• Dual RJ45 ports for Ethernet, sensor buses, or custom I/O
• Clean front-panel access with precise connector alignment
• No supports required – fast and reliable FDM printing
• Stackable enclosure matching the base system design language
