The Open CM9.04 B is the new open source microcontroller from ROBOTIS, creators of the DARwIn-Mini! This controller is powered by a 32bit ARM Cortex-M3 processor. Any 3-pin TTL DYNAMIXEL servo can be used with the Open CM9.04 B. Programming the board can be done in the ROBOTIS OpenCM software. This IDE is based off the Arduino IDE, so any Arduino users should be right at home.


Instruction manual located here.

  • OpenCM9.04 is an open-source controller that runs a 32bit ARM Cortex-M3.
  • It is possible to use the 3-Pin connector to control ROBOTIS' Dynamixels which supports TTL communication.
  • Uses a USB Cable (Mircro-B) (included), which is used for some smartphones to download programs onto the board.
  • The board is easily programmable with [ROBOTIS OpenCM], an Arduino-like IDE that allows the user to easily program in C/C++.
  • JTAG / SWD terminal can be used run commercial developmental programs.
