It does purport to use the same chip as the Teensy++ 2.0, a AT90USB1286, though in none of the pictures was the chip clear enough to read, which is another red flag for me.
Ha, "red flag", is that a China joke? :?)
Here's the best I can do with enlargement and contrast enhancement:
Make any difference? You guys know more about this than I do.
Yes, it's a counterfeit, not just a clone, as the listing claims that it's a "Teensy USB development board")...
Is "Teensy" an actual trademark? If so, the developer hasn't bothered to
indicate that anywhere. I suspect it's no more a trademark than "Soarer's Converter"—yet all kinds of people have built and sold those "by name", and as long as they've worked as expected, no one's objected. Calling this a "Teensy 2.0" is just a way of making its purpose clear to peeps who'd be interested in such a thing.
Definitely a deal if it works, but I'm still not sure I'd be inclined to roll the dice when a legit one is only twelve bucks more.
Depends on how you see it—you could also say the other ones are twice as much. ;?)
Anyway, I've seen people here take chances on new keyboards whose quality was unknown, that involved much more dough than this. So I just thought I'd put it out there in case anyone was intrigued enough to pursue it for the price of a lunch. See ya later!
