EthWiFiManager enables Ethernet-first connectivity on ESP32, with automatic Wi-Fi fallback to maintain stable network access in industrial environments.

TurtlPass

ESP32-S3 and W5500 based machine monitoring IoT sensor node PCB that collects vibration and temperature data and transmits equipment status over Ethernet.

Robust industrial PLC using STM32 MCU and W5500 Ethernet controller. Supports 12 inputs, 16 relays, and Modbus TCP/RTU for stable real-time control systems.

The pool monitor with LED matrix visualization. Uses WIZnet Ethernet for stable, real-time remote data logging and sensor tracking in high-moisture environments

ESP32'en fungerer som en dual-mode Modbus gateway med to separate RS-485 interfaces:

WIZ850io enables stable Ethernet connectivity for grblHAL CNC controllers by offloading TCP/IP to W5500 hardware, ensuring deterministic motion control.

Lightdream Pocket streams real-time Art-Net LED frames using WIZnet W5500 hardware TCP/IP — eliminating MCU jitter for deterministic, multi-universe synchronize

ESP32_Host_MIDI

This project turns a Raspberry Pi Pico-class RP2040 design into a dual-port wired Ethernet board using two WIZnet W5500 controllers

This project is a hands-on comparison of two common ways to add wired Ethernet to an ESP32: an RMII PHY (LAN8720) versus a SPI Ethernet controller(WIZnet W5500)

ESP32-S3 + W5500 Hybrid Controller! Features automatic network failover and native ROS2 support for reliable robotics.

Bridging the Gap: My #30DaysOfEngineering Journey Begins

Zephyr PR #104394 brings W6100-EVB-Pico2 support! It pairs RP2350 with W6100 (IPv6) and enables high-speed 70MHz SPI.

Turn a $15 ESP32-S3 into a universal MIDI hub: USB Host, BLE, Apple MIDI, OSC, ESP-NOW, DIN-5, USB Device, Ethernet, and MIDI 2.0
