Node MCU V3 CH340

NodeMCU is a programmable firmware running in Lexin esp8266 chip.
It is based in Lua language, and provides a high level API to encapsulate the hardware operation of esp 8266. It allows developers to connect with the underlying layer in a way similar to Arduino Hardware interaction makes it easy for software developers to operate hardware devices; at the same time, NodeMCU also provides event driven network API and nodejs style programming Cheng way is to let Internet developers like fish in water. At present, NodeMCU dev kit, the first generation development board launched by NodeMCU, extends esp12, the esp8266 package module launched by anxinco technology including:

*D1-D10: can be reused as GPIO, PWM, I2C, 1-wire
*A0: 1-way ADC
*USB power supply
*USB serial port debugging interface

The available RAM is 20kB; at present, 512k flush is adopted, and the user's available storage space is 150kB. At the same time, use flash programmer from Flash write firmware.
The low cost esp8266 hardware and highly abstract NodeMCU API will boost the creative ideas of many developers and make your prototype development fast!
