The NodeMCU/ESP8266 community took the IDE selection a step further by creating an Arduino add-on. If you're just getting started programming the ESP8266 or an established developer, this is the highly recommended environment. Visit our dedicated page on setting up and configuring the Arduino IDE for a NodeMCU EPS8266. NodeMCU Carrier Board. NodeMCU Carrier Board with Serial Ports. The. * The ESP8266 chip requires 3.3V power supply voltage. It should not be powered with 5 volts like other arduino boards. * NodeMCU ESP-12E dev board can be connected to 5Vusing micro USB connector or Vin pin available on board. * The I/O pins of ESP8266 communicate or input/output max 3.3V only. i.e. the pins are NOT 5V tolerant inputs NodeMCU Development kit provides access to these GPIOs of ESP8266. The only thing to take care is that NodeMCU Dev kit pins are numbered differently than internal GPIO notations of ESP8266 as shown in below figure and table. For example, the D0 pin on the NodeMCU Dev kit is mapped to the internal GPIO pin 16 of ESP8266

Note this that is the NodeMCU pin number and not the ESP8266 GPIO number. Multiple pins can be set at the same time. Note that any valid GPIO pin can be used, including pin 0. delay specifies the number of microseconds after setting the pin values to wait until moving to the next state. The actual delay may be longer than this value depending on whether interrupts are enabled at the end time. ESP8266 NodeMCU Pinout. The ESP8266 NodeMCU has total 30 pins that interface it to the outside world. The connections are as follows: For the sake of simplicity, we will make groups of pins with similar functionalities. Power Pins There are four power pins viz. one VIN pin & three 3.3V pins. The VIN pin can be used to directly supply the ESP8266 and its peripherals, if you have a regulated 5V. This tutorial however will facilitate you to connect all the versions of ESP8266 NodeMcu, i.e V1 , V2 or V3. For makers, having ESP-12 module, rest assured, 12E is no different from its precursor.
