Io Pin Nodemcu Esp8266 Wifi Development Iot Board

It comes with bigger flash size, more IO pins and a smaller board size! The NodeMcu is an open-source firmware and development kit that helps you to build your IOT product only with a few Lua script lines or directly in C through the Arduino IDE. When used with Arduino, you can also use many of the Arduino libraries! The board includes everything - power regulators, USB interface, LEDs, Switches, etc to start programming and running the codes using the ESP8266 WiFi Module.This makes is very simple and easy to build IoT project using sensors, SD Card modules, etc. The NodeMCU also plugs directly into a standard breadboard and lets you easily connect external modules for testing.
