ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the s 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 front-end module, is designed to occupy minimal PCB area. ESP8266 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. This ESP8266 NodeMcu development board can be use for small temperature and humidity monitor in home automation project and works very well Compatible with Arduino development platform. ESP8266 CH340 chip, power your development in the fastest way combinating with NodeMcu Firmware; It's a IOT unit with all available resources on board, support smart link and smart networking.
