A couple quick questions.  1.  What size resistor is needed to switch the tinylily mini usb adapter from 3.3v to 5v?  And does the little resistor next to it need to be de-soldered?  I need 5v TTL for a surface mount uln2803 and 74hc595 combo i'm using.  2.  I don't have my micrometer handy at the moment..  Is the hole pattern like 12-13mm center to center?  I haven't had a chance to look at the eagle files for the unit yet.
