I have built several Adventure Bots and have not had any issues, but when I tried to build a custom 2 WD robot using IoTiny I've run into a strange problem.
Using the same "continuous rotation servo with Wheel" set from my Adventure Bot I found that they worked for about a minute before refusing to run any more.
I thought it might be just a coincidence, so I took another working set and first tried that with a EZ-B v4 controller in a Power Shell with the same "LiPo Robot battery" (after a full recharge) that I was using on IoTiny ... and those wheels worked fine
But, when I connected the wheels back to the IoTiny, the servos worked for a little while and then stopped working!
What's worse, is that I reconnected the servos back into the Adventure Bot and NONE of then worked anymore.
Any ideas?

The old 360 servos all work great with the ioTiny. Not sure what the problem is, but I wouldn't try anymore new ones with the ioTiny until something is fixed.
both are fixed with latest hardware revisions. Using the old revisions together will cause this scenario. Contact Us if you used the old revision and experienced issues.
@Alan...
... Hind sight in all I personally I would have quit after burning up the first servo... But hey I was dumb...I'm guessing @Alan may have been using an Adventurebot to test. That would take out 2 at a time.
I burned up several too in my initial testing because I couldn’t believe the results I was getting.
I just assumed I had bad parts as others were saying the didn’t have the issue
Thankfully, Jeremie confirmed the problem
I burned 4 using this setup:
I had only 4 .... now i have 0
Fellow Builders, we are gather here today to pay our respects to ptp’s full rotation servos and thus his robot platform. Though his platform was not with us long, it left a memorable impression on all of those who saw it because it looked cool. Indeed, many wish his servos worked even at this moment so he could finish his project and post videos!
The life of a servo at times may seem short but for ptp these servos never matured to warrenty expectations. When one servo dies, another is manufactured and perhaps even will go on sale. We must remember to keep our part stocks up, so that we may never say we have zero servos!
Please, a moment of silence for ptp’s servos.
lol
Yeah, well. I so go big or go home
, and hindsight is always 20/20.
Was the end of a long day, and the first time in many months I have had any time to spend with my robots. Decided I should test all of the servos I got in my HDD upgrade box (SIX, Roli, and Dev Kit upgrade) before the warranty ran out. I had already rebuilt Six, and was running through the rest of the servos. First one died, and I recalled there was a problem mentioned on the forum, but didn't go look it up. Seemed to recall that it was just some of 360's, not all of them (whoops) so tested all 5, and all 5 died. They sort of worked setting the port between 90 and 180 (movement was jerky, but working) and then as soon as I went in reverse, they stopped responding.
