I bought the EZ-Bv 4 for two weeks ago! It is amazing and very good stuff
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!)
adaptor
Just do your research before doing anything with it.
so the adaptor is just enough for jd then.
The 25c or 35c tells you how many amps can safely be pulled from the battery at one time. If the battery is a 1.3 amp per hour battery or 1300mah battery, you could safely pull about 30 amps at one time. That is a huge amount.
If you want to use a power supply while programming movements, it will prevent you from having to charge the battery every few minutes if you are pulling this many amps.
The concern is that you have to have a power supply that produces enough amps for all of the load you will be using. The fuse in the base is a 20 amp fuse, so theoretically that would be the max you can pull.
The other thing to understand is that the motors will draw current when holding a motor or moving a motor. It's not as simple as just adding up values, but also taking into account bursts of electricity.
Then you will have all the power you need and you won't overload the v4.
Dear Bhouston,
Could you please share a photo of the Instruction Diagram for my ref?
Thanks a lot:)
Connect your battery power into a bus bar that has positive on one side and negative on the other, connect all your servo and motor power to this bar.Also connect a ground (negative) wire from either your batteries or the bus bar to the negative pin on the EZB v4. Connect all of the servo/motor signal wires to the easy builder.
Hope that helps you.
Anyway, thank you for your great help
