When you’re tinkering with ESP32 microcontrollers, choosing the right setup can make the difference between a smooth-sailing project and a barely-functional experiment. And I’m not just talking about the circuitry components, sensor modules, or other accessories, either. The very ESP32 board that you’re using for your DIY project can influence the scope of your project, and although many microcontrollers from this family have plenty of hardware similarities, their specs can differ quite a bit.
