There, I am starting this STM32 Board, which I dont know the exact type of STM32 to choose, I need to replacing old machine board (its microprocessor base) with 10 of weight sensor, and 20 stepper motor, and 2 communication and 1 additional output,

Welcome, @Siun6, at the community!

Your needs will be met by at least 150 types of STM32, but you might start to look at devices like:

I would recommend starting with the tool STM32CubeMX, which will help you select the right device and create a framework program with the initializations of all relevant peripherals.

BTW: it might make sense to revise the stepper motor drivers too, because a lot has happened there in recent years.

Good luck!
