How to Run Wired Ethernet Communication with WIZnet W5500 on ESP32 MicroPython? Summary This robotics-oriented project connects an ESP32 MicroPython board to a WIZnet W5500 Ethernet module to add wired TCP/IP communication through SPI. The ESP32 runs the MicroPython application, uploads W5500 driver files through Thonny IDE, and uses a socket-style interface for network testing. W5500 provides the wired Ethernet MAC/PHY, hardware TCP/IP stack, socket resources, and internal packet buffering needed for stable robot-node communication over Ethernet instead of relying only on wireless links…
