USB Cable Included

Reviewer: from FLAGSTAFF, AZ USA

Not shown in the photos, nor mentioned in the product listing, the UNO ships with a 20" USB Cable. No need to buy one separately, unless you need a longer one of course.

Not labeled on headers

Reviewer: from Maryland

My units do not have the signal labels printed on the headers, so -1 since this is a strong preference of mine and why I bought this item. Mine did include the USB cable. In case someone is wondering, sometimes a Lexan backing plate is included that the SMT variety Uno board snaps into. Not included or expected.
