NodeMCU DEVKIT

  • ESP8266 NodeMCU Dev  has an Ai- thinkers ESP8266 module on it
  • It comes with the latest version of AT Firmware already setup on it, together with all the drivers we are going to use
  • Note: The D0, D1, D2, … numbers printed on the board are different from what ESP8266 Module uses – because originally those boards were made for a different pins determine.
  • Make sure to refer to the image above to determine which pins are which On top it has a micro-USB socket, for connecting to the computer.
  • Next to it are two buttons, one for reset and one for flashing.
  • Then on both sides of the board are two rows of pins, to which we will be connecting cables.

The symbols meaning is as follows:
  • 3v3- this is a fancy way to write 3.3V, which is the voltage that the board runs on internally. You can think about this pin like the plus side of a battery. There are several pins like this, they are all connected inside.
  • gnd- this is the ground. Think about it like the minus side of the battery. They are also all connected.
  • gpioXX- “gpio” stands for “general purpose input output”. Those are the pins we will be using for sending and receiving signals to and from various devices that we will connect to them. They can act as output – pretty
  • much like a switch that you can connect to plus or to minus with your program. Or they can act as input, telling
    your program whether they are connected to plus or minus.
  • a0- this is the analog pin. It can measure the voltage that is applied to it, but it can only handle up to 1V.
  • vin- this pin is connected with the 5V from your computer. You can also use it to power your board with a
    battery when it’s not connected to the computer. The voltage applied here will be internally converted to the 3.3V that the board needs.
  • rst- this is a reset button (and a corresponding pin, to which you can connect external button).
  • flash- hold down this button while resetting to bring the board into programming mode (also known as flashing mode).

The other pins are used internally by the board, and we will not be connecting anything to them.
