Horter's EUR 24.90 I2ARL kit ships its LAN slot empty and its ATmega328P has no Ethernet MAC, so Modbus TCP needs the separate EUR 11.90 W5500 module.
Why Does the Horter I2ARL Need a Separate W5500 Module for Modbus TCP?

boneIO's gen 2 dimmer moved to an ESP32-S3, which has no Ethernet MAC, so its shipping firmware declares a WIZnet W5500 on SPI in place of gen 1's LAN8720.
Why Does the boneIO gen 2 DIN-Rail Dimmer Use a W5500 Instead of LAN8720?

Going's Senbrino ladder IDE has an MCP server inside, so an AI edits the ladder itself. Senbrino then builds Arduino C++ for a W5500 Modbus TCP board.
How Does Senbrino Turn AI-Edited Ladder Logic Into an Arduino Sketch on a W5500 PLC Board?
