Hi! Im looking for a microcontroller with a lot of gpio. I have looked into NUCLEO-H755ZI-Q. As I understand it shall provide me with 144 gpio but im not sure if I need some header for this to happen? I have read about ST Zio and morpho connectivity but not sure what exactly that means? How can I access all gpio? What exactly do I need or do NUCLEO-H755ZI-Q provide all these outputs out of the box?

 

Are there any microcontroller with even more gpio?

    The NUCLEO-H755ZI-Q is a board - not a microcontroller.

    Do you actually mean a board, or a microcontroller (ie, just the chip itself - for incorporating into your own design)?

     

    EDIT (sorry - posted too soon):

    It provides a total of 144 pins - they may or may not all be available for use as GPIO

    They are explained in the User Manual:

    The connector pinouts are all documented in the User Manual.

    See also the schematics.

    Again, do you mean boards, or do you mean microcontrollers ?
