All the digital pins on one of my 3 EZB V4's stopped working. I rebooted and reset the unit and still can't get the 3 volts at any of the digital pins when I try to turn them on through EZ Builder. I probably burned something up on the EZB but was wondering what type of mishap would cause them all to stop responding? I'm a little leary to just swap out the EZB with a replacement in fear that if I have a bad servo or transistor somewhere in the robot that it would damage the new EZB. Only thing I can remember doing is taking all the servo cables off the unit then reattaching them so I could reroute the wires and I also updated EZ Builder (after a year of not doing any updates). After checking all cables they are plugged in right and I don't recall plugging any in backwards and having to correct it.
I do remember thinking after doing the update after a year of not doing them how much smoother and faster servos were responding now, so I did have digital control for a while after the update. *sick*

One of my EZ-B has one bad digital port, and I know it is because I shorted it accidentally.
Does the EZ-B make sound? Can you tell if the analog ports are good? Camera? Wondering if the main cpu is bad (I believe that you can get a wifi connection even without the main board operating).

This unit is one of the first V4's to roll out of China when they were introduced. It would suck if it's DOA. I'm kinda proud of being one of the ones who waited for so long for it through that Pre-order year. It's also heavily modified with the Sound breakout mod and a power pigtail added. Maybe I caused a problem when soldering on it but it's been running nicely for well over a year. *tired*
1) does the ez-b v4 make a bootup sound when it turns on?
2) when ARC "connects" to the ez-b v4, does it do so successfully?
3) do servos work on the v4?
4) do analog ports read data on the v4?
If you can perform all of the above, we can start looking into the project code.
I had two options, raise the voltage or enable battery monitoring in the connection control and set the min voltage lower than what I want to supply.
