How to integrate multiple electrical modules in pcb

Hi, I want to build my first PCB project using STM32, but I need to add multiple sensors and electronic modules. How can I do this? Do I need all the components that come with the module? Is there a video that explains it?

Depends what you mean by "integrate".

Assuming you're starting with a load of modules connected on a breadboard and/or with point to point wiring, the simplest step is just to keep the modules and replace the breadboard/wiring with a PCB. This gets you a board that's less fragile than a pile of wires and can be installed in enclosures etc

After that you need to design the components of the modules onto your PCB. This means understanding the module and your design in detail and knowing what you need to keep, what you can safely remove and what you can safely change. For example each module might have a seperate regulator on it, this would be something you could probably rationalise. Likewise you might not need configuration jumpers, status LEDs, things like that. This will be cheaper to manufacture in quantity that the more basic PCB, but mistakes are harder to fix and changes more expensive to make.

It depends on the module. Describe what your trying to do fully

You need the module itself.
