At least try it.  You'll know if the gyro is working immediately.

It probably failed hi-pot or final test and went back for rework/reflow.  That's not uncommon in lines that actually have a QA department.

Thanks. So, it shouldn't have come to me?

Like I said, try it.

At the company I worked at if the tag came off a product there was hell to pay, and we would never actually write on a unit.  I'm guessing they lost the tag or don't use them and wrote right on the thing.  Marker doesn't come off a PCB, so if they replaced it then the marker will still be there.

If it got reworked then it's probably better quality and more tested than something straight from the line.

Only way to know is plug it in and see if the gyro works.  You'll know right away.  Bad parts happen, only thing to do is replace them if possible, otherwise you'd be throwing out a lot of boards.

Finally, it appears non-working. 

Overall, I've bought 2 boards and both are flawed. 

help@3drobotics.com doesn't answer.

Is it possible to return it anyway? have anyone tried?

I'd wait for a response.

But there's no reason you can't send it back if you want.  Keep a receipt for your shipment.  If they don't credit you just file a dispute with whomever you used to pay.

File a dispute only as a last resort though.  I accidentally filed one even though I told them not to do it because I couldn't identify a charge and they couldn't give me the proper details.  The poor guy called me up pissed because it was a legit charge and it costs them $20 for any dispute, win or loose.
