Arduino NodeMcu ESP8266 Pin Mapping
Arduino NodeMcu ESP8266 Pin Mapping Arduino NodeMcu (ESP8266) Pin Mapping If you use NodeMcu borad with Arduino IDE the following chart will help to find the pin maping eg. NodeMCU Pin D1 is equivalent to arduino Pin 5. Built in LED of NodeMCU is connected to D4 in arduino programming it equivalent to Pin 2 NodeMCU Arduino D0 = 16 D1 = 5 D2 = 4 D3 = 0 D4 = 2 D5 = 14 D6 = 12 D7 = 13 D8 = 15 D9 = 3 D10 = 1
