Explain the problem:

*Is it a code issue? - make sure you are using the right libraries and Mblock or Arduino software, please post a screenshot.

In the Otto blockly interface I cannot add ESP32devC or M5 stack as supported boards.

Specifically, I would like to use this open hardware version: ESP32-WROVER-DevKit-Lipo but I believe it is pin-compatible with all ESP32devC boards.

Additionally I'd like to play with the M5 stack core boards

As an aside, I wonder if some kind of HAL system would be possible as used here
