Description of the OpenCM9.04-A control board for Dynamixel servomotors:

The OpenCM9.04-A control board for Dynamixel servomotors is an embedded board based on ARM Cortex-M3 32bit CPU.

The board comes in 2 flavours: The OpenCM9.04-A control board for Dynamixel servomotors which is simply the PCB with SMD components (no connectors, switches or headers pre soldered) and the OpenCM9.04-B control board for Dynamixel servomotors (An end-of-life product) which comes with all 3pin connectors pre soldered and switches ready to use. Type B boards also come with headers that users can optionally solder in case they wish to access the additional GPIO pins on the edges of the board.

Also, the OpenCM9.04 is a platform with open-source hardware and software. Based on Processing and Wiring languages the ROBOTIS OpenCM, an Arduino-like IDE that allows the user to easily program in C/C++, facilitates robot development with ease. ROBOTIS OpenCM is supported in Windows, Linux and MacOS computer platforms.
