If you want to control RS485 Dynamixel servos get the USB to RS-485 3Mbps instead.


If you want to control TTL Dynamixel servos we suggest you to get the Dynamixel Starter Set that comes with the U2D2 and some other accessories.


Connect your DYNAMIXEL servos to your computer or SBC.

Up to 6Mbps on the servo BUS


U2D2 is a small size USB communication converter that enables to control and to operate the DYNAMIXEL with the PC. It is smaller than the previous model and has mount holes to make it easier to install on robots. It uses the USB cable to connect to the PC and prevents damage of the USB terminals. It has both 3Pin connectors for TTL communication and 4Pin connectors for RS-485 communication embedded for easier control and access for the Dynamixel X series. (Supports UART as well.) Requires the convertible cable for Molex connector using Dynamixels.
