Combined with U2D2, it can supply various kinds of external power supply to supply stable power to DYNAMIXEL.


Item Details
Operaing Voltage 7.4V ~ 24.0V
Maximum Current 10.0A


Part Name Description
Power Connectors In order to use various power sources including SMPS, three types of connectors are attached.
DYNAMIXEL Connectors JST connector 3-pin, 4-pin are provided for communication in two ways
TTL/RS485 Test Points TTL data line, RS485 D +, D-line signals can be easily identified with a separate TP


  1. When using the terminal block, the left-side is ground and right-side is source, so be careful of polarity when using an external power supply.
  2. Since the back of the board is exposed to several pins, it is recommended to combine the provided supporters so that the conductor does not touch the floor to some extent.

How to Assemble

  1. Assemble four(4) plastic supporters at each corner of the U2D2 Power Hub Board as shown below.

  2. Use plastic rivets to mount U2D2 on the U2D2 Power Hub Board.

  3. Connect U2D2 and U2D2 Power Hub Board with 3P or 4P cables (Both 3P and 4P cables can be connected at the same time).

  4. Connect additional cables that will connect U2D2 and DYNAMIXEL (Depending on DYNAMIXEL model, converting cables may be required).

  5. Connect the other side of the cable to DYNAMIXEL (Depending on DYNAMIXEL model, converting cables may be required).

  6. Connect power to U2D2 Power Hub Board.

    DANGER : Do NOT use multiple power inputs at the same time. Select ONLY one of the power source to connect.

    WARNING : Check the Recommended Voltage for DYNAMIXEL before supplying the power.

  7. Turn the power switch on U2D2 Power Hub Board to supply power to DYNAMIXEL
