Select programmer in Arduino IDE

When you have selected a board in Arduino IDE, external programmers can be selected under Tools > Programmer in the menu bar. The options are defined in the platform’s programmers.txt file[1].

The programmer selection is used by:

  • The Tools > Burn Bootloader option.
  • The Sketch > Upload Using Programmer option.

The programmer selection is not used when:

  • Compiling your sketch (for example, when clicking Verify button Verify).
  • Uploading without a programmer, by clicking the Upload button Upload button.

Note: In Arduino IDE 1.x, if the selected board only supports programmer uploads, the Upload button Upload button has the same effect as Tools > Upload Using Programmer[2]
