This thread is an indirect continuation of this one:  
[Motor drive for sewing machine](https://community.simplefoc.com/t/motor-drive-for-sewing-machines/4621/110)

Unfortunately, I have not yet received any feedback on my circuit.

I have now finished routing the circuit board. But I have no experience with routing power drivers.  
The circuit board should be able to withstand a continuous current of 12A.

**Here are the data sheets for the main components:**

**Layer structure:**

Top (1oz): Signals  
Inner1(0.5oz) GND  
Inner2(0.5oz) GND  
Bottom: (1oz): Signals

If you provide the kicad source it will be much easier to review.

I have now uploaded my Kicad project to Github 🙂
