(Good for Piso Wifi Wireless Subvendo)
NodeMCU V3 ESP8266 ESP-12E is a 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 the 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).
