What does “Q” mean?

What does the word “Q” mean in the NUCLEO board, for instance, in “NUCLEO-H755ZI-Q”? How is it related to the MCU? Sorry for my ignorance, I’m new in the stm32 world.

Hello @embdd-programmer and welcome to the ST Community :smiling_face_with_smiling_eyes:.

The "Q" means in the NUCLEO board name (for exemple in the "NUCLEO-H755ZI-Q" ) that this board has an internal SMPS function. To understand more about this codification, you Can take a look at the table 2 of the DB3171.

Best regards.
