Set up Arduino IDE for node MCU ESP8266 (CP2102)

Set up Arduino IDE for node MCU ESP8266 (CP2102).

Aim: To set up Arduino IDE for node MCU ESP8266 (CP2102).


Laptop/Computer with the Internet.


Once you go through all the steps in this tutorial, you can run Arduino IDE code on node MCU.

Step 1: If you do not have Arduino IDE installed on your computer, click the link below and download it.

Arduino ide

Choose “Windows Win 10 and newer, 64 bits” in the Download options.

Once you have Arduino IDE software installed, follow the steps below-

Step 2: We will start by adding the ESP8266 board to Arduino IDE.

Link:   this link. Open Arduino IDE > File > Preferences > Additional board manager.

Paste this link in the additional board manager and click OK to save changes.


Step 3: This tutorial is for ESP8266 (CP2102 driver). So, we need to install the driver for CP2102 on our device/ computer.

Follow the link given below and download

Silicon labs

In the software downloads section choose “CP210x Windows drivers”. Start Download.

Extract and open the downloaded file and install the “CP210xVCPInstaller_x64” application.

Install x64

Step 4: Go to Arduino IDE. On the left-hand side select boards manager and search for “esp8266 by ESP8266 Community”.

Select the latest version and install it.

Step 5: Select board “NodeMCU 1.0 (ESP-12E Module)” and port (accordingly). As shown in picture below-

Select OK.

Board and port


Arduino IDE is now ready to program Node MCU ESP8266 (CP2102).
