Installing ESP8266 plug-in for Arduino IDE

This is a plug-in for Arduino IDE, allowing it to "understand" the ESP8266 board.

  • In your Arduino IDE, go to File> Preferences
  • Enter into the "Additional Boards Manager URLs" field as shown in the figure below. Then, click the "OK" button
  • Note: if you already have the ESP32 boards URL, you can separate the URLs with a comma as follows:,
  • Open the Boards Manager. Go to Tools > Board > Boards Manager...
  • Search for ESP8266 and press install button for the "ESP8266 by ESP8266 Community":
  • That's it. It should be installed after a few seconds.
