Is your feature request/improvement related to a problem? Please describe.

The new H5 series is not yet included in the generic variants. I got a Nucleo-64 STM32H503 here in front of me from embeddedWorld '23, and can't program it using Arduino :-(

Describe the solution you'd like

It would be great if generic H5 variants were added, and even better if you could add the Nucleos as well :-)
