Nodemcu out NodeMCU devkit, try playing board is a board that incorporates ESP8266 (ESP-12) + USB to Serial + NodeMCU firmware together. Make applications easier. I do not have a lot of peripherals to 10 GPIO ports adequate for NodeMCU devkit acquired a blank board using AT Command to operate independent life, not much. But the Board has developed NodeMCU Firmware you to write Lua put into making applications easier
The devkit there are 10 port to port GPIO Digital and is the key to a Wifi Serial Therefore, I have Wifi Router to the Internet.You can create projects Internet of Thing to easily finish in a single board.
You ever play ESP8622 using Firmware of NodeCMU it easily adaptable bit. Because of how similar many of the tools used. If you are using AT Command was using the Arduino Sketch of Serial Monitor is a tool that must be used.
Or use other tools Serial Interface can be used as well as it can.
Try to play first before installing the driver USB to TTL.
