Having populated the board and testing the design there need to be some revisions.

Revisions:

1. Mirror the pins on the USB connector.
2. Change the layout of the USB connector as the chassis pins do not fit the board.
3. Narrow the holes on the DC connector as the fit is poor.
4. Increase font size for the silk screen as the text is illegible.
5. Shrink the inductor footprint and move it closer to other components, shrinking the board.

However, the circuit works properly, generating a solid 3 V! Only 1% error with no load (multimeter).
