    The Open CM9.04 B is an open source micro-controller from ROBOTIS powered by the 32-bit ARM Cortex-M3 processor. Any 3-pin DYNAMIXEL servo using the TTL communication protocol can be used with the OpenCM9.04-B. With plenty of processing power, this controller is a great choice for robot building using multiple servos!

    Each kit includes:
    • 1 x OpenCM9.04-B micro-controller
    • 2 x 20 pin male header row
    • 2 x 20 pin female header row
    • 1 x USB micro-B cable
    • 1 x Instruction manual

    Program the board using the free ROBOTIS OpenCM software, an easy to use Integrated development environment (IDE) based on the Arduino IDE. Arduino users should be right at home. The OpenbCM9.04-B can be be powered and programmed over USB but remember: servos cannot be powered through the USB connection and must be powered separately.

    Compatible servos:

    The OpenCM9.04-B is not a replacement for the OpenCM9.04-C board used in the DARWIN MINI. That controller can not currently be purchased separately. It is also not compatible with the new R+ Motion 2.0 software package. Individual XL-320 servos can be always be used with the OpenCM9.04-B and the OpenCM software.
