NodeMCU. 30 Pins (ESP8266 WiFi Programming & Development Kit) CP2102

NodeMCU is an open source development board and firmware based in the widely used ESP8266 -12E WIFI module. It allows you to program  the ESP8266 WIFI module with the simple and powerful LUA programming language or Arduino IDE. 

With just a few lines of code you can establish a WIFI connection and define input/output pins according to your needs exactly like Arduino, turning your ESP8266 into a web server and a lot more. It is the WIFI equivalent of ethernet module. Now you have internet of things (iot) real tool. 

With its USB-TTL , the nodeMCU Dev board supports directly flashing from USB port. It combines features of WIFI access point and station + microcontroller. These features   make the NodeMCU extremely powerful tool for WIFI networking. It can be used as access point and/or station, host a webserver or connect to internet to fetch or upload data.

Features

• Finally, programable WIFI module.
• Arduino-like (software defined) hardware IO.
• Can be programmed with the simple and powerful Lua programming language or Arduino IDE.
•  USB-TTL included, plug & play.
• 10 GPIOs D0-D10, PWM functionality, IIC and SPI communication, 1-Wire and ADC A0 etc. all in one board.
• WIFI networking (can be used as access point and/or station, host a web server), connect to internet to fetch or upload data.
• Event-driven API for network applications.
• PCB antenna.
