The DYNAMIXEL communication bus allows you to daisy chain multile servos, making wiring a breeze. However sometimes you need to split your DYNAMIXEL chain into multiple directions. Just plug a 3-Pin Dynamixel Cable from your controller to any port on the hub, and you'll have 5 ports avaialble for DYNAMIXEL servos.
This hub has the added benefit of 2 power breakouts. You can plug in bare wire with the screw terminal block, or plug in power through the DC barrel jack. The 2.1*5.5 female barrel jack will accept the standard Robotis SMPS power supply.
The AX/MX Power Hub is compatible with the following DYNAMIXEL servos:
This hub is NOT compatible with the 4-pin RX and EX series of DYNAMIXEL servos.
