V4 Servo/Sensor Power Board

Hello everyone:D

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

Hey Guys, it truly is 6.6VDC, i just haven't had a spare moment to update the datasheet, sorry.

I am very confused. I was going to power my EZBs with +12volts from the wheelchair batteries.

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?

you must use a power source that will work with your servos (5v, 6v, 7.4v depending on the servo), use a regulator to reduce the voltage of the digital port or have an external power distribution set up to provide the required voltage.

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 I set it to 5 volts or 6volts, will that trip the low voltage warning?

If your VIn (supply to the EZ-B) is below the low battery warning level then yes. If you use regulators on the VCC pins or use an external power distribution method for sensors and servos then no.
