Project description

Introduction This project builds a wired display and LED control portal using an ESP32-S3 microcontroller, a WIZnet W5500 Ethernet Controller, a 4″ ST7796 SPI TFT display, and WS2812 LED strips. It favors wired reliability and low latency over Wi-Fi, making it ideal for dashboards, visual controllers, or industrial indicators. Planned extensions include HTTP/REST APIs, PC applications, and smart home integration. WIZnet Product Integration The WIZnet W5500 is connected to the ESP32-S3 via SPI and handles Ethernet communications through its hardware TCP/IP stack. With support for multiple…
