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.
