How much is the maximum current we can use in 3.3 v supply for stm32h743z board?

I am using stm32h743z for interfacing the RGB and Infrared camera ?

My Main Question is how much total current (maximum current) we will get or we can use from 3.3 v power supply ?

I have checked the data sheet but still i cant able to find so kindly help me so that it will be helpful for my knowledge

Data sheet would have current numbers, but depends on how fast you clock things, what peripherals you have enabled, and more generally what you attach externally​.

CubeMX has a current estimation tool.

You might want to measure current draw on a Nucleo board or your own prototypes.​
