STM modules, to be precise 5″ ones have 2 types of microcontrollers installed on their boards. One is STM32U599NJH6Q and the other is STM32U5A9NJH6Q.
Most common question regarding this module is if those two microcontrollers are compatible with each other and if it is possible to make project in TouchGFX for each of those modules.
Yes, both are compatible witch each other, and to make a project within TouchGFX we use template for 5″ STM32U599.
