While real ESP32s operate at 3.3V, the simulation model usually handles the logic for you, but you should still ensure your virtual circuit respects the 2.2V to 3.6V operating range for accuracy.

: Many Proteus models hide power pins. They are connected to global power rails by default.

Simulating the ESP32 in Proteus is ideal for students and engineers who want to verify logic before moving to hardware.

Schematic snippet (conceptual):

In the Arduino IDE, go to Sketch -> Export Compiled Binary to generate a .hex or .bin file.

Then he remembered: the forum post said “rename the .HEX to .BIN and rebuild the library index.”
