PCB custom - tm4c12333h6pm
The key to make custom PCB is to :


Follow carefully  the PCB guideline
Try to use 4 layers, using 4 layers make the overall design a lot easier because you don't need to worry about inductance on your power/ground.
Use software like Saturn PCB toolkit to calculate with efficiency your impedance width where you need to control impendance ( USB tracks).
Choose a manucfacturer that can let you have the right quantity of copper per inch/square
Take your time to carefully read the doc that concern sensitive part of your design, in my case it was the USB differential tracks.
Finaly, take to solder properly all your component.


These are the "major" guideline that I found out while doing the PCB. After I manufacturing the PCB, I ended up with a working PCB and where my USB got ported from the dev kit to a custom PCB.
