Arduino Boards.txt editor is a free Windows based application that can be used to edit the Boards.txt and Programmers.txt files in Arduino IDE (Integrated Development Environment) which is an open-source software meant to develop and upload your code to the Arduino boards.

Arduino Boards.txt editor is compatible with Arduino IDE 1.0 to 1.5x as well as other compatible IDEs such as Visual Micro and more.

Boards.txt contains the definitions and metadata for Arduino boards that are supported by the IDE platform. These definitions include Name of the board, Board ID, Parameters for building / uploading sketches and more.

Programmers.txt comprises the definitions used by external programmers for burning bootloaders or sketches on a blank development board.


  1. Create, Rearrange, Edit, Duplicate and Disable boards in the Boards.txt file
  2. Import board definitions from other files. Additionally, copy and paste board definitions directly from clipboard and web pages.
  3. View / Print pinout diagrams for the most popular Arduino boards and processors.
  4. Manage the sub-menus for board selection that were introduced in Arduino 1.5x IDE
