I don’t know that this title make you think off, but i couldn’t express better the subject. We’re talking about SD cards that are not what you’d expect them to be.

The job looks like it is hand soldered so the guys from sparkfun think there must have been a huge batch of microSD cards and a perceived shortage of full size SD cards.
