+title: "Select programmer in Arduino IDE"
+---
+
+When you have [selected a board in Arduino IDE](https://support.arduino.cc/hc/en-us/articles/4406856349970-Select-board-and-port-in-Arduino-IDE#board), external programmers can be selected under _Tools > Programmer_ in the menu bar. The options are defined in the platform's `programmers.txt` file[^1].
+
+[^1]: [Platform specification – programmers.txt](https://arduino.github.io/arduino-cli/latest/platform-specification#programmerstxt)
+
+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](img/symbol_verify2.png) **Verify**).
+* Uploading without a programmer, by clicking the ![Upload button](img/symbol_upload2.png) **Upload** button.
+
+> **Note:** In Arduino IDE 1.x, if the selected board _only_ supports programmer uploads, the ![Upload button](img/symbol_upload2.png) **Upload** button has the same effect as _Tools > Upload Using Programmer_[^2]
