<\/figure><\/div>\n\n\nAccording to the Arduino website: “The Arduino IDE 2.0 is an improvement of the classic IDE, with increased performance, improved user interface and many new features, such as autocompletion, a built-in debugger and syncing sketches with Arduino Cloud<\/em>“.<\/p>\n\n\n\n If you want to install the ESP8266 boards on the “classic” Arduino IDE, follow the next tutorial instead:<\/p>\n\n\n\n If you prefer programming the ESP8266 using VS Code + PlatformIO, go to the following tutorial:<\/p>\n\n\n\n You might also like reading the ESP32 Guide: Installing ESP32 Board in Arduino IDE 2.0 (Windows, Mac OS X, Linux)<\/a><\/p>\n\n\n\n Before proceeding make sure you have Arduino IDE 2<\/a> installed on your computer.<\/p>\n\n\n\n Go to the Arduino website and download the version<\/a> for your operating system.<\/p>\n\n\n If you have doubts, you can go to the Arduino Installation Guide<\/a>.<\/p>\n\n\n\n Do you need an ESP8266 board? <\/strong>You can buy it here<\/a>.<\/p>\n\n\n\n Recommended reading: Best ESP8266 Boards Comparison<\/a><\/p>\n\n\n\n To install the ESP8266 board in your Arduino IDE 2, follow these next instructions:<\/p>\n\n\n\n 1. <\/strong>In the Arduino IDE 2, go to File <\/strong>> Preferences<\/strong>.<\/p>\n\n\n 2.<\/strong> Copy and paste the following line to the Additional Boards Manager<\/strong> URLs field.<\/p>\n\n\n\n Note:<\/strong> if you already have the ESP32 boards URL, you can separate the URLs with a comma, as follows:<\/p>\n\n\n\n 3. Open the Boards Manager. You can go to Tools <\/strong>> Board <\/strong>> Boards Manager…<\/strong> or you can simply click the Boards Manager <\/strong>icon in the left-side corner.<\/p>\n\n\n 4. Search for ESP8266 <\/strong>and press the install button for esp8266 by ESP8266 Community<\/strong>.<\/p>\n\n\n That’s it. It should be installed after a few seconds.<\/p>\n\n\n\n To test the ESP8266 add-on installation, we’ll upload a simple code that blinks the on-board LED (GPIO 2).<\/p>\n\n\n\n Copy the following code to your Arduino IDE:<\/p>\n\n\n View raw code<\/a><\/p>\n\n\n\n Select your board before uploading the code. On the top drop-down menu, click on “Select other board and port…<\/strong>“<\/p>\n\n\n A new window, as shown below, will open. Search for your ESP8266 board model<\/p>\n\n\n Select the ESP8266 board model you’re using, and the COM port. In our example, we’re using the NodeMCU 1.0 board. Click OK<\/strong> when you’re done.<\/p>\n\n\n\n Now, you just need to click on the Upload <\/strong>button.<\/p>\n\n\n After a few seconds, the upload should be complete.<\/p>\n\n\n The ESP8266 on-board LED should be blinking every second.<\/p>\n\n\n You can click on the Serial Monitor icon to open the Serial Monitor tab.<\/p>\n\n\n That’s it! You’ve installed the ESP8266 Boards successfully in Arduino IDE 2.<\/p>\n\n\n\n If you want to add support to upload files to the ESP8266 LittleFS filesystem, you can follow the next tutorial:<\/p>\n\n\n\n 1)<\/strong> If you try to upload a new sketch to your ESP8266 and you get this error message “esptool.FatalError: Failed to connect to ESP8266: Timed out waiting for packet header<\/em>“. It means that your ESP8266 is not in flashing\/uploading mode.<\/p>\n\n\n\n Having the right board name and COM port selected, follow these steps:<\/p>\n\n\n\n Your ESP8266 should have the new sketch running. Press the ENABLE\/RESET<\/strong> button to restart the ESP8266 and run the new uploaded sketch. <\/p>\n\n\n\n 2)<\/strong> If you get the error “COM Port not found\/not available”, you might need to install the CP210x Drivers:<\/p>\n\n\n\n This is a quick guide that shows how to prepare Arduino IDE 2 for the ESP8266 Boards on a Windows PC, Mac OS X, or Linux computer.<\/p>\n\n\n\n Next, you might want to read: Getting started with ESP8266<\/a> or learn more about the ESP8266 board with our resources:<\/p>\n\n\n\n There is a new Arduino IDE\u2014Arduino IDE 2. In this tutorial, you’ll learn how to install the ESP8266 boards in Arduino IDE 2.X and upload code to the board. This … <\/p>\n\n
