The ESP8266 NodeMCU CP2102 board has ESP8266 which is a highly integrated chip designed for
the needs of a new connected world. 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.
ESP8266 has powerful on-board processing and storage capabilities that allow it to be
integrated with the sensors and other application-specific devices through its GPIOs with
minimal development up-front and minimal loading during runtime. Its high degree of on-chip
integration allows for minimal external circuitry, and the entire solution, including the
front-end module, is designed to occupy minimal PCB area.
The ESP-12 Lua NodeMCU WIFI Dev Board Internet Of Things with ESP8266 is an all-in-one
microcontroller + WiFi platform that is very easy to use to create projects with WiFi and
IoT (Internet of Things) applications
