EZ-B v4 works with standard PWM servos, dynamixel, ubtech and lewansoul servos. Chances are, it works with the servos you are thinking of. Post picture or links to your servos. However, there's a lot of cheaply made servos so we recommend EZ-Robot HDD servos or Dynamixel servos only.

Actually that is good info just before I go on a mad servo buying spree!

                                                                                let me ask: can ez-b be used with this type of servo?

Yes, the EZ-B v4 or IoTiny will work with both of those servos. however, be warned that those servos are incredibly low quality and will most likely burn out within the first month of use. We recommend Dynamixel or EZ-Robot HDD servos.
