Double-click the ESP32. Manually enter 80 in the "Clock Frequency" field and set the units to MHz .
For professionals, purchasing the official license is the only supported method for functional simulation within the Proteus environment. For all other cases, use the library for what it's great for: creating professional schematics and designing PCBs.
Complex protocols like I2S or capacitive touch pins may lack behavioral accuracy depending on the version of the third-party library downloaded. Troubleshooting Common Errors "Component Not Found" in Library Search esp32 proteus library
Have you tried a specific ESP32 Proteus library that worked well? Share your experience in the comments below!
Instead of forcing Proteus to simulate an ESP32, use this hybrid approach: Double-click the ESP32
Proteus natively supports many popular microcontrollers (PIC, AVR, 8051, ARM Cortex-M), but the ESP32 is not included. This is because:
He added a DHT22, an OLED, a relay. Wired them. Loaded a hex file from a real ESP32 sketch (just a WiFi scanner). Hit . For all other cases, use the library for
Click the button (P icon) on the left toolbar. Type ESP32 into the keywords search box.
If you’re looking for an today: ✅ Check GitHub for community-maintained versions ✅ Expect no official library from Labcenter (Proteus’s maker) ✅ Be ready to tweak pin mappings and simulation scripts ✅ Or just do what Leo almost did—use the real hardware and skip the simulation for WiFi-heavy projects
Until then, the third-party ESP32 Proteus library remains the only viable solution for embedding ESP32s into a full PCB simulation workflow.
