Yes it has the card and nice little anti static bag.Did it come with a 'Welcome to Teensy 4.0' Card? The T_4.0 in hand should 'nearly' match the image on that card.
Okay, good to know.Sports Internet Solutions is on the list of official distributors (they buy in bulk from PJRC), so it should be a genuine Teensy.
Love this board so far! Nice upgrade!
