Lab2 peer-review

First of all I have to tell you that you have a nice layout on your PCB.

Somethings to think about instructions on Lab 2:

• #4 to fix filled zone in rectangle on front and back copper layer for GND
• Still on #4, your PCB design still have one gray line on the USB.
• #5, Cut out for the sensor, Look how to do it in instruction.

Something good to know is to avoid using 90 degree trace angles.

Hope I helped a little.
