After whole weekend of working with the new V4 EZB I've been able to get two installed and working over my home network. It was a learning experience and had it's challenges but more on all that in another post, another time.
What I'd like to say here is this;
I'm powering the EZB with a power converter from wall voltage. I don't use batteries so I have a continuous power feed and can supply almost any voltage needed within EZB's power range of operation.
The data sheet for V4 says the voltage for the V4 is between 4.5 & 16vdc. This may be true but if the voltage gets below somewhere between 6 & 7 vdc the board will stop responding and I get a irritating voice loop saying ""My batteries are low, My batteries are low".......... This goes on and on till the voltage is raised and the board is power cycled.
So the bottom line is you cannot power EZB V4 with anything lower then 7vdc or it just stops and nags you for more power. Sounds like my 3rd wife,
This also means we cant power the V4 with less then 7 volts and get a lower output voltage on the digital I/O pins. We for sure need voltage regulators for devices needing lower voltages.
Upgrade to ARC Pro
ARC Early Access will give you immediate updates and new features needed to unleash your robot's potential!
However, the battery monitor can be disabled in the Connection Control Configuration - it's a checkbox. Otherwise you can specify the minimum voltage for the battery saver.

Note that the Low Battery Warning only has two options of either Disabled or Enabled after clicking on the "Connection Control" button, with no settings for adjusting the voltage level. Just to be sure of the voltage actually present, I am measuring the voltage right at the back of the DC plug with load with a digital volt meter.
Is there now another place to adjust the low voltage level setting for when the message of low battery warning comes on?
Your battery may be reading 7.2 (but that is probably without a load on it)... Your battery could still be low, however. As soon as you put a load on it like the EZB4 and servos it will quickly drag the voltage down to and below 6.6v.... This is the default low voltage setting for each of the 5 EZBs in the connection control.... Charge your battery...
Keep in mind that with my example below, you lose the battery saving features of the EZ-B v4. If you drain your LiPo battery too far, it will be damaged.
Check my started topics, it's in there somewhere.
Is there a way to play an mp3 kept on an iphone?
I'm guessing that the Soundboard command will only play files that are on the PC and you'd have to use an MP3 trigger board if you wanted to store the sound filies on the robot itself.
If using the EZB Sound servo and Soundboard the files do not require the PC. In fact, I believe that may work while running from an android device (however I don't use the mobile app so don't know what's currently supported and what isn't).
