NUCLEO-H755ZI-Q how many gpio

[pero]

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 ?

Sorry. I meant the boar

I accidentally posted to soon - see the edit for more details on the board ...

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

But can I just access these the same way as on arduino or esp32? For example just solder a female header on st expansion header and use it as normal on esp32 or arduino? How many are actually available and not reserved for other stuff?

Again, see the User manual:
