Go to and select your specific ESP32 board (e.g., ESP32 Dev Module ).
If you plan to design advanced IoT prototypes next, consider exploring how to route on your PC to link your Proteus ESP32 simulation directly to live internet databases or MQTT brokers.
Standard Proteus libraries usually simulate the physical pins and basic code logic. They rarely support active, live Wi-Fi or Bluetooth network communication without complex third-party network bridge software.
void setup() pinMode(2, OUTPUT);
: Use the Virtual Terminal in Proteus to debug Serial data.
void setup() pinMode(13, OUTPUT);
If you want, I can:
: Obtain the .LIB and .IDX files from reputable sources such as The Engineering Projects or GitHub . Locate the Library Folder :
But there’s a catch: Proteus does not natively include an ESP32 model in its default library. This article explores the current landscape of ESP32 libraries for Proteus—what exists, how to use them, their limitations, and best practices for reliable simulation.
on the ESP32 component to open its Edit Component properties window. Look for the field labeled Program File . esp32 library proteus
However, Proteus doesn’t include an ESP32 model by default. In this post, I’ll show you how to add a custom ESP32 library to Proteus, simulate a simple LED blink, and even send serial data.
If you can see the component but can't simulate it, check if the library includes a .MDF (Model File). Without this, Proteus only treats the ESP32 as a footprint for PCB layout.
Proteus currently has no native Virtual System Modeling (VSM) model for the ESP32 series chips. The ESP32‘s architecture—specifically the Tensilica Xtensa LX6 core—is a proprietary architecture licensed from Cadence. Unlike ARM Cortex or AVR architectures, which have open and well-documented simulation models, the Xtensa architecture has not been officially modeled for Proteus. Go to and select your specific ESP32 board (e
If the folders above do not work, look here: C:\ProgramData\Labcenter Electronics\Proteus 8 Professional\Library (Note: You may need to enable "Show hidden files and folders" in Windows File Explorer). Step 2: Copy and Paste the Files
Let’s test the library with a classic LED blink.
