11+ Esp8266 Pin Diagram. Personally, i really like this component, as it already comes with usb input. Pin numbers in arduino correspond directly to the esp8266 gpio pin numbers.
But it is important to explain that the nodemcu is formed by an esp12e, which still has an esp8266ex inside it. Esp8266ex has 17 gpio pins which can be assigned to various functions by programming the appropriate registers. Figure 1 esp8266ex block diagram.

11+ Esp8266 Pin Diagram. 0, 1, 2, 3, 4, 5, 12, 13, 14, 15, 16, which correspond to the actual gpio pin numbers of esp8266 chip. The pin out of the same is shown below. Esp8266 is an 8 terminal module. Thus, we'll learn the correct pin.
