In accordance with a request from organizations and people I respect, here’s a photo take on 2015-04-19 showing the packaging from an Arduino UNO I purchased from Adafruit Industries (in the United States of America) on 2010-10-19 showing the text “Manufactured under license from Arduino by SMART PROJECTS S.r.l.”.
Here is the order information from that purchase. For more info, see the Hackaday post Your Arduino Packaging Could Sway a Court Case and the Adafruit post Please post old Arduino packaging that says “Manufactured under license from Arduino” #TeamArduinoCC.
