USB breakout board (dock) for onion omega 2

The goal for this dock is to allow for ‘simple’ bread boarding of the onion omega 2 boards. I have included a 5v to 3.3v voltage regulator for power and a CH340G usb to serial IC for communications. Communications and power are provided through the micro USB connector and the regular USB connector provides access to the onion’s USB line.
