UNO R4 WIFI with ARDUINO IDE 2.x DEBUGGER?

[w_postma]

I am looking to upgrade from an older Arduino Uno (R3) to the UNO R4 but I am confused by the documentation for the Arduino IDE which lists a lot of models that support debugging inside the Arduino IDE but the UNO R4, with its shiny 32 bit CPU does not seem to be one of them? First what are they thinking? Second? Is it true?

Is the documentation wrong/outdated (UNO R4 WIFI works with DEBUGGER in ARDUINO IDE) or is it really true they came out with a R4 update in 2024 and didn't add onboard debugging support to the IDE for it?

Hi @w_postma. The documentation is outdated. You can use the UNO R4 WiFi with the Arduino IDE integrated sketch debugger. This board is especially convenient to use because the board's ESP32-S3 module acts as an on-board debug probe. So you don't even need a separate debug probe to use the IDE's debugger.
