What is the motor driver module for 12v, 150 watts, 0.32A motor 775?
Or can you build me a schematic, this is one direction motor, I just need to control it with arduino...

Those numbers don't work. 150 watts at 12V is 12.5A. 12V x 0.32A is <4 watts. Provide a link to the datasheet for your motor so we can see what is really going on.
Once you sort that out, for speed control but not direction just search for "arduino MOSFET motor" and you'll find thousands of useful schematics

Package Contents:
1* 775 motor
Only the above package content, other products are not included.
Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
We'll have to guess that the 0.32A is the no-load current (so no use to anyone really). It looks like a conventional 700 series motor so 150W is reasonable. Call it about 12.5A maximum running current, quite a bit more on startup.
So pick a schematic and look for a logic level MOSFET to suit. I'd aim for at least 50A Ids for the MOSFET to give you a better chance of getting away without needing a big heat sink. Something like an RFP50N05L would probably do the job but there are plenty of other choices.

The stall current for a 12V 775 motor is 43A.
You can get H-bridges like below and just use them in one direction.

Better to not guess and go to a website with reliable data on their products... Who knows if the picture even matches the reality?

As a professional designer that's exactly what you'd do. But when it's just a hobby...if you refused to use anything that didn't have a reliable detailed specification you'd spend a lot more money and IMO have a lot less fun. Most things really are pretty much what they seem to be. You just have to recognise that experimenting is part of your hobby.
