Futaba S3003

Hello I recently purchased Ez-robot, I tried several servant with the card but I can not make them work, the models are:

H-King hk15138 Tower Pro SG90 TowerPro 998 and in the end also Futaba S3003 All such servant I tested them on Raspberry Pi and worked perfectly, in Ez Build connected servo add servant but it just goes crazy and then maneuvered the board flashes.

Is there something wrong? stress


Upgrade to ARC Pro

Don't limit your robot's potential – subscribe to ARC Pro and transform it into a dynamic, intelligent machine.


The ex-b v4 doesn't regulate power to the servos, so if you are using a high voltage battery the servos will get that power. If those servos are 5v they will be overvolted. Also, make sure that your plugging them in the correct way. If you don't, they will not move.


As technopro covered, what power source are you using?

Did you connect the servo correctly to the ez-b?

What controls did you use to move the servo in ARC?
