This is D1 Mini V2 NodeMcu 4M Bytes Lua WIFI Internet Of Things Development Board Based ESP8266, it is a mini WIFI board based on ESP-8266EX. 11 digital input\/output\u00a0pins, all pins have interrupt\/PWM\/I2C\/one-wire supported(except\u00a0D0<\/strong>) 1 analog input(3.3V max input) and a Micro USB connection.<\/p>\n

The development board\u00a0features WiFi-SoC\u00a0ESP8266 and is made for\u00a0fast Internet-of-Things (IoT) prototyping. It\u00a0is flashed with the latest\u00a0firmware version\u00a0and can be set up and programmed right away\u00a0with\u00a0the onboard micro USB\u00a0connection. With only a few\u00a0lines of code,\u00a0the NodeMCU\u00a0Dev Kit connects to your\u00a0local network\u00a0and ready\u00a0for control by other network members\u00a0like\u00a0computers and smartphones.<\/p>\n

The d1 mini is an ESP8266 development board that is compact, versatile and very easy\u00a0to use with the Arduino IDE. It supports natively by the Expressive SDK.<\/p>\n
