I know that the V4 has a direct voltage input from the battery to the digital pins. I was unsure however if this also incuded supplying direct voltage to the outer pin as well?
I was looking online to make something to where i can run my servos and or sensors at a different voltage then what was supplied from the board. I planned to run 12 volts into the board but realized I would need to step down the voltage in every pin that requires 7.2 or 5v. servo City sells a servo Power Board for around $20-30 and I was wondering if anyone had experience with using it. I think it may solve the problem of powering multiple pins at another voltage than what the board is supplying? It says that "cleanly power your servos on more than 6 volts and not burn up your receiver" I could be completely wrong in thinking that this may work so any thoughts would be welcome! It would definitely be a easier way to power things if this could work though

@Robot-Doc that is really cool! much like i was going to try to achieve but i think mine would have been 2 separate pieces...
It's more of a distribution board than a power board though. Very simplistic!
So if I use a 12V font to power it, I can not plug the 6v servos straight to V4?
I have to use external power or feed the Ez-b with only 6v?...
Be aware, sensors are likely to be 5V. The EZ-B will nag you that your battery is low if you supply it with 5V.
There are regulators on the V4 however these are used for the EZ-B components, as far as power out is concerned there is no regulation (there is a max and min voltage for the V4 though! 4.5v and 16v respectively) but I thought it best to just mention these regulators for a complete answer.
My plan around it is to supply the v4 with 7.2-12volts from a lipo battery and then split off power for sensors, led's, etc
im just making sure but isn't the signal wire still regulated?
I really dislike that nag phrase. I'm supplying 6.5 vdc to EZB now and something somehow fluxed with the voltage input of my robot and the hag keep nagging me about voltage. I had to power cycle to shut her up. *mad*
I really wish the battery tender settings were adjustable through the web interface to the EZB hardware instead of ARC.
Now, I have to go 7.2v or 6volts (what ever it is for the 995 servos.) for the EZB3s.
And ? for the EZB4. ?
I am not sure I understand what you are saying. Is the 6.6 the minimum you can go before the low battery alarm? because I have lots of sensors that require 3.3-5V.
Here is what I have:
I have plenty of regulators.
I have a +12 supply from the wheelchair.
I have 13 995Metal servos,arms,neck and sonar. 6 or 7volts, I don't know.
I have a sabertooth 2X25 for the wheelchair motors,
I have two EZB3s and a EZB4.
Millions of sensors.
What do you recommend?
*confused* *confused* *confused*
You must either supply the EZ-B V4 with whatever voltage your servos need.
Use regulators on the VCC pin of each digital port.
Provide an external power source distribution for sensors/servos.
If you use regulators on the VCC pins or use an external power distribution method for sensors and servos then no.
