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?

My IO Tiny runs the servos with no problems. Could the tape be a problem?
@Frank... You're not crazy man... I just tested with the metal geared servos from my developer's kit I just got... Same thing happened to mine as it did to yours... Actually after running them at different speeds with the iOtiny trying to figure this out they no longer work period.. When I plug them back into the ezb4 they are dead, no worky..... I don't really care as I don't use 360 servos in my projects... My old resin 360 servos still however work fine with the iotiny and ezb4...
Anyway lets hope @Jeremie and @DJ will look into this...
It's not the IoTiny. There's a minor change in the latest revision of the continuous rotation servo pcb. It took Jeremie a loooong time to identify what was happening, and its such a rare situation for the IoTiny and these servo combination.
Contact us to warranty the continuous rotation servos.
However, in the meantime we are looking to see if there's a possible firmware solution, or if the servo pcb revision needs to be reverted.
Stay tuned.
@DJ... Thanks... I appreciate you guys efforts on stuff like this... Not to get off topic or anything. This is also the first time using the new HDD servos ... Not sure if anyone else noticed as the "no buzz feature" has been all the buzz
lately but these new servos position so accurately as well. Way better than the old HD servos. They are very smooth indeed... Simply fantastic to say the least...
P.S. I broke those 360 servos and I would never use them anyway... Thanks for the warranty offer but I am good... No need...
@Richard_R Thanks for confirming this...
@Dj, Thanks for the great support on your products. I did ruin a few in my testing as I couldn't believe what was happening as others didn't see the issue.
I will contact warrentee support
I agree that the new HDD servos are amazing
Regards, Frank
I'm expecting two new HDD rotation servos.
DJ mentioned the possibility of reverting the servo's PCB.
Is there away to know if is the old(good) or new(pcb) before i connect them to the Iotiny ?
@ptp I know the lever arm and 180 degree servos are now HDD but I haven't seen any mention of HDD for 360 degree servos
@Jeremie mentioned that the plastic gear 360 degree servos work with IoTiny
Regards, Frank
I finally got around to testing all the servos from my HDD upgrade order, and sure enough, the 5 360 servos all died when tested with an ioTiny.
