According to Labcenter‘s support forums, Proteus does not natively support ESP32 simulation. Even when using MicroPython simulation features, proper compiler configuration is essential. The MicroPython compiler must be correctly pointed to the installation path: C:\Program Files\Labcenter Electronics\Proteus 9 Professional\Tools\MicroPython
ESP32 microcontrollers run at high clock speeds (up to 240MHz). Your computer CPU may struggle to simulate this in real-time. If Proteus displays an "Excessive CPU load" warning, double-click the ESP32 and lower the clock frequency setting in the properties box.
: Obtain the .LIB and .IDX files from reputable sources such as The Engineering Projects or GitHub . Locate the Library Folder :
Lower the clock frequency in the ESP32 component properties. Mismatched baud rate or swapped TX/RX lines.
To get the ESP32 module appearing in your component list, follow these steps: Download the Library Files : You will need a
While Proteus does not natively include an ESP32 model, you can add it by installing third-party library files. This allows you to create circuit diagrams, design PCBs, and simulate basic I/O logic, though specialized features like Wi-Fi and Bluetooth cannot be simulated within the software. How to Add the ESP32 Library to Proteus
Upload and test your Arduino IDE or ESP-IDF hex files directly onto the virtual microcontroller.
Below is a universal installation guide based on the methods described across multiple community sources.
void loop() Serial.println("ESP32 simulation works!"); delay(2000);
Look at the console log output window at the bottom of the screen.
Go to and select your ESP32 model (e.g., ESP32 Dev Module ).
