The ESP32 has rapidly become the go-to microcontroller for IoT projects, blending Wi-Fi, Bluetooth, dual-core processing, and low-power operation into an affordable package. However, prototyping with physical ESP32 modules can be time-consuming, expensive, and sometimes risky—especially when dealing with high-current loads or complex sensor networks.
