How to Build a Telnet Server with W5500 on ESP32-S3 CircuitPython? Summary This project shows how an ESP32-S3 running CircuitPython can use the WIZnet W5500 Ethernet controller to implement a Telnet server. The ESP32-S3 runs the Python application, command parser, and debug loop, while the W5500 provides the wired Ethernet interface, hardware TCP/IP stack, socket resources, and packet buffering needed to expose a simple TCP service on port 23. What the Project Does The source article tests W5500 CircuitPython driver behavior on an ESP32-S3 board using two Telnet server implementations…
