Show HN: Esp32sim – Run ESP32 firmware in the browser
Developers introduced Esp32sim, an open‑source tool that emulates ESP32 microcontroller firmware directly within a web browser. Leveraging WebAssembly, the simulator loads compiled ESP‑IDF binaries, enabling users to test and debug code without physical hardware. The project aims to streamline development workflows and educational demos, offering a portable environment for rapid prototyping in real‑time of IoT applications.
