Ez-bv 4 And Power Adaptor

Assistance Requested

rickymahk2013 claims to have checked these sources:

I bought the EZ-Bv 4 for two weeks ago! It is amazing and very good stuff Smile

Actually, I want to use that to build my human robotic.
Therefore, I have few questions would like to ask!

Would anyone can help me?

Q1 : Can I use this Adaptor for EZ-Bv 4?
Q2 : EZ-Bv 4 can support several pieces of motor servo (refer to the attached picture)?
Q3 : Will "EZ-Bv 4" damaged by the 12v external power adaptor of Huge Servo Motor? (Because I will use it to control all servos at the same time!)

I have found a few conversations, tutorials and activities that may help with your question. Take a look at these links. I've sorted them by what I believe to be most relevant but that is not always the case as I'm still learning.

Also, consider reviewing the Learn section for informative lessons and activities. Check it out!


Your servos and motors will require much more current than what the plug-in adapter will provide (1.2 amp)


The plug in adapter wouldn't even have enough power to run even one of the servos to be honest.


Do some research on Amps. Your issue isn't volts, it's Amps.


this one do you need



If you are going to build a human type robot, you might want to consider providing power using batteries instead of a plug-in power supply. You will need to also research H-Bridges to control your motors. You may consider 12vdc batteries for your motors and 6 vdc for your servos.


You could use a pc power supply and use a yellow and black wire and get about 15 amps worth of power. You would need to Google which pins to cross on the atx power supply to allow you to use it without it being plugged into a motherboard.

Just do your research before doing anything with it.


this is the adaptor recomended for jd


@nomad, I doubt 6A would be enough either to be honest looking at what he is attempting to power. The inrush current of the servos and motors will be huge. I would be surprised if an AC power supply would be capable.


am suprised avery time ,howmany possebility's there are.
so the adaptor is just enough for jd then.
