Debugging - “1-click” solution for debugging with a zero configuration.

Tools & Debug Probes

Supported debugging tools are listed in “Debug” column. For more detailed information, please scroll table by horizontal. You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).


You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions.

External Debug Tools

Boards listed below are compatible with Debugging but DEPEND ON external debug probe. They ARE NOT READY for debugging. Please click on board name for the further details.
