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 ...
