NodeMCU V3 ESP8266 ESP-12E CH340 WiFi Board

Short Description:

NodeMCU V3 ESP8266 ESP-12E is a WiFi development board used in prototyping IoT projects through the Lua programming language or through Arduino IDE. 

Long Description:

ESP8266 NodeMcu is a popular and widely used development board based on the ESP-12E WiFi Module that combines elements of easy programming with Arduino IDE (C\C++) and WiFi capability. Through the build-in programmer and CH340G USB-to-Serial chip, flashing the ESP8266 and serial output on a PC, development and prototyping projects are done with ease. Just like Arduino boards, the ESP8266 NodeMcu has GPIO pins, voltage regulator, ADC, and Micro-USB port (for flashing and serial output) – all on one board. On top of that the ESP8266 NodeMcu has a full WiFi that takes care of the WiFi communication to a server or client.
