Harmonic Drive & Brushed DC Servo Motor Driver

The SERVO Motion Control Board is maybe the fastest and lowest-cost way of getting your DC servo motor up and running. The clear, explicit documentation and the Windows test utility program take the mystery out of servo motor control. The board is designed for easily adding additional axes of control without flipping dip switches or setting jumpers. By mounting these compact, modular boards near your motors, you can greatly simplify the rat’s nest of wiring which plagues most multi-axis control systems. The PIC-SERVO SC Motion Control Board also includes motor power monitoring, soft current limiting, and position error limiting which eliminate the need for an additional real-time processor. If used with the RS232-485 Serial Adapter or with a Step & Direction signal generator, a set of SERVO Motion Controllers can even be operated as a stand-alone control system. All this comes at a price comparable to stepper motor controllers.

sorry for my poor english.

could I ask you to please qualify me that does this project is complete and buildable or should I buy the specific PIC or IC program from jRKERR IC?
