Hello friends, I hope you all are doing great. Today, I am going to share the NodeMCU ESP8266 V3 Library for Proteus V2.0 . The NodeMCU is the board most of us met the ESP8266 on: an ESP-12E module, a USB chip, a 3.3 V regulator and two rows of pins with names like D1 and D4 - plug it in, pick it in the Arduino IDE and your sketch is on Wi-Fi. Our first NodeMCU library from 2023 could only show the board and run an Arduino UNO sketch on its pins. This version runs your ESP8266 sketch - ESP8266WiFi, ESP8266WebServer, ESP8266mDNS, D0 to D8, A0 - and puts the board on a Wi-Fi network inside Proteus. Updates NodeMCU ESP8266 V3 Library for Proteus Latest version: V2.0 (October 2026, this tutorial) Earlier versions: V1.0 (2023) Other ESP8266 modules: ESP-01 · ESP-01S · ESP-07 · ESP-07S · ESP-12E ...
