Servo Motor Kit
The SMK (Servo Motor Kit) is designed for developer who wish to learn servo motor control and
build their robot machine. It includes one servo motor driver daughter card and one servo motor.
The motor driver card can drive 24 RC servo motors at most. The motor daughter card can be
linked to the FPGA development kit via the 2x20 Pin GPIO connector.
The PWM IP and some example designs on different FPGA development boards are also provided
in the kit. By referring these demos, the user can quickly learn how to work with the servo motor
and build their own robot machine.
