NodeMCU V3 ESP8266 ESP-12E is WiFi development board that helps you to prototype your IoT product with few Lua script lines, or through Arduino IDE. The board is based on ESP8266 ESP-12E variant, unlike other ESP-12E, you won’t need to buy a separate breakout board, usb to serial adapter, or even solder it to a PCB to get started, you will only need a usb cable (Micro USB).

This is an Alexa Controlled Switch using ESP-01 development board.
