Wifi Module Esp8266 Pin Diagram. A potentiometer or variable resistor is connected with the analog pin a0 of the nodemcu esp8266. To upload the device arduino requires the uart communication pins rx and tx only.
If you re using an esp8266 01 board you can use the following gpio diagram as a reference. A simplified circuit diagram for using the esp8266 01 module is given below the switch sw2 programming switch should be held pressed to hold the gpio 0 pin to ground.
