How to Run MicroPython on ESP32-C3 with W5500 as a Wired Ethernet Gateway? Summary This project documents how to build a wired MicroPython environment around an ESP32-C3 and the WIZnet W5500. The main value is not a finished application but a practical firmware path: aligning the correct MicroPython and ESP-IDF versions, building firmware successfully, flashing the right image set, and bringing up W5500 as the Ethernet interface so the ESP32-C3 can act as a wired gateway under MicroPython. What the Project Does The source is a build-and-integration record for running MicroPython on an…
