U2D2 is a USB converter device that serves as a bridge to connect and control Dynamixel servo to PC / laptop. U2D2 can be connected to laptop / PC by using micro USB cable. U2D2 supports both TTL and RS-485 interfaces as a communication path to various Dynamixel servo-servo variants. In addition U2D2 also supports UART interface as a communication path to OpenCM9.04, CM-150 and CM-200.
U2D2 can be used to configure & test servo conditions, firmware upgrade and recovery, servo ID replacement, and various other functions.
