 This interface option is directly compatible with Robotis Dynamixel AX, MX series of servos. It can also connect to XL and XM series of servos provided you create a necessary adapter cable or board to connect them. This interface option is directly compatible with Robotis Dynamixel AX, MX series of servos.
