Is there any documentation on how much power/amps the EZ-B V4 will supply for servos?
I see a lot of you are using up to 20+ servos (and some are the big hobby ones) and was wandering about how you handle the power for the servos?
EDIT ***5 amp continuous/board with spikes up to 20amp***
One of my ezb4s is driving 20 + servos on my inMoov
See here... EZB4 Data sheet
If you find you are drawing much more than this we would recommend externally powering your motors directly from the battery power supply to the motor drive electronics (it's good idea to add a fuse in between them).
Servo power is best to come from a 7.4V LiPo battery (with protection) but you'll need servos that are rated for 7.4V, if you don't have servos that can handle this high of a voltage you'll need a
voltage regulator.
The thing to watch out for with regulators is how much current draw they can handle, like most motors, servo motors can draw huge spikes of current when first initialized so you'll likely want to double or triple the current rating of your voltage regulator compared to the operating current of the servo so you don't experience a brown out. Brown outs result in the voltage dropping below a certain level and will either effect the operation of the servo or the electronics controlling them.
Somehow I missed the datasheet, and thanks for direct link.
I'm currently using a Phidget servo controller on my prototype build platform and want to try the EZ-B controller. Will be moving this arm to a SuperDroid platform soon.
Sorry somehow the image got rotated...
I love the look off the arm. Looks like that can hold some weight.
