STM32 & W5100S HAT for micro-ROS

Project description

Source Mention Original Blog Post by Ar-Ray This curation is based on a technical blog post by Ar-Ray, where he documents the process of enabling Ethernet on STM32 for micro-ROS using WIZnet hardware. 1. Introduction: Breaking Hardware Boundaries The Concept: Typically, developers use dedicated shields for their specific MCU boards. Ar-Ray challenged this by taking a WIZnet Ethernet HAT (form-factor designed for Raspberry Pi Pico) and wiring it to an STM32 Nucleo board. The Goal: To achieve a stable, hardwired micro-ROS connection on an STM32 device without waiting for a specific STM32…
