Nucleo-H7S3L8 Board in Arduino IDE

Hi 
I just added the STM32 based boards in Arduino IDE, but I cannot find the NUCLEO-H7S3L8 listed.
Is it supported? or am I missing something ?

The Place for STM32Duino (ie, Arduino on STM32) questions is: https://www.stm32duino.com/

 

Or, for general Arduino questions: https://forum.arduino.cc/

Arduino IDE specifically: https://forum.arduino.cc/c/development-tools/ide-2-x/93

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

    Hello @isso ,

    The NUCLEO-H7S3L8 board is not yet supported in Arduino.

    As mentioned by Andrew, you can check and request this in Arduino sites.

      @isso the list of supported boards is here:

      https://forum.arduino.cc/c/development-tools/ide-2-x/93

       

      In addition to the forums mentioned earlier, I see there is also a GitHub Discussion board:

        Thanks for the reply and apology for any inconvenience posting this here.
        So, I decided to get starting with the STMCube IDE instead, are there some support examples for this board ?
