Dear ez-robot,
I got "EZ-Robot Developers Kit" recently. I have a question about battery.
For now, it is using "battery" for electricity. Could it be change to use "AC adaptor"?
Please help and looking forward to having your answer very soon.
Best regards,

The EZ-B V4 can accept 4.5v to 16v with the ideal voltage at around 7.4v
You will also need to make sure the current output of the AC Adaptor is high enough to power the EZ-B V4 plus any other accessories driven by the adaptor. Most AC Adaptors are rather low current outputs, 1A, 2A or 3A usually, in some instances 5A. If you have a lot of servos this can require a great deal more than 5A and will cause problems.
Also, by using an AC Adapter you restrict the range your robot can physically move (if it is a moving robot). It stops becoming portable if it needs plugging in to a wall outlet.
But yes, you can use one just take the above in to consideration.
Nice to meet you both and many thanks for your helpful answer!
I will try to do with your solutions.
But I have an experience that I do mistakes to plug in wrong adaptor, then the board is broken. Besides, I will do it again by using your opinion!
Thanks and good day!
There are more here: 7.5 volt power supplies
adaptor
You would want something like what DJ mentions above.
oeps they dont send to belgium,but i got the idea.
dj adaptor
i cant read AMP
Depending on what you plan to drive it may work however that may only be enough to power one or two servos.
And I will use this Linear Servo!
Is it work with adaptor?
certificate is not reddy yet.so i need to look for 6.00 amp
