Introduction :
Wi-fi module, based on ESP8266 system. On Board 10 GPIO ports (each of which can handle PWM, I2C and 1-wire), built-in 10-bit ADC and a converter USB-UART. It has installed software NodeMCU which enables programming with the Lua script language or using the Arduino IDE.
NodeMCU (ESP8266 WiFi) is a highly integrated module It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.
