well received and well packaged. plastic bubble to protect the pins. card sealed in an anti static bag. by against any record or manual. on the manufacturer's website, not much either. we must search on google. shame! last point on amazon, it specifies for Arduino "uno", on the manufacturer's website version "uno" is not cited as compatible! (Compatible Tested for Arduino Mega, Duemilanove & Diecimila) yet to try the product.
