OpenCM9.04 is an open-source controller that runs under 32bit ARM Cortex-M3.
All hardware and software are disclosed.

Uses an exclusive 3PIN connector to control the ROBOTIS DYNAMIXEL XL-320.

Uses USB Cable (Micro-B) to download programs onto the board.

Users can choose between using the ROBOTIS RoboPlus software or ROBOTIS OpenCM IDE.

JTAG / SWD terminal can be used to run commercial developmental programs.

The OpenCM 485 Expansion Board, which supports TTL and RS-485, can be used to control all types of DYNAMIXEL's, such as AX, MX, and Pro series.

When using the OpenCM9.04-C to control the DYNAMIXEL, a separate power supply must be supplied to the DYNAMIXEL.

RoboPlus can be used when the board is connected to the PC via USB Downloader LN-101 or BT-210.
(PC must have Bluetooth device for Bluetooth connection)
ROBOITS OpenCM IDE can be used only via Micro 5PIN USB Cable.

The RoboPlus and ROBOTIS OpenCM IDE CANNOT be used simultaneously.

The firmware must be changed depending on the software to be used.
(Please refer to the e-Manual for changing the firmware)
