Project description

ESP-WROOM-02 Ethernet Expansion Using USR-ES1 Project Overview This project demonstrates how to add wired Ethernet connectivity to an ESP-WROOM-02 (ESP8266-based) module using the USR-ES1 Ethernet module. Although the ESP-WROOM-02 is designed primarily for Wi-Fi communication, certain applications require stable, low-latency, or security-controlled wired Ethernet connections. By integrating an external Ethernet module via SPI, the ESP-WROOM-02 can operate in a wired network environment. This project verifies hardware connectivity, SPI communication, Ethernet initialization, and basic TCP/IP…
