DESCRIPTION
The EVKT-MOTOR-00A is a communication
interface device that provides an interface
between a USB and a serial peripheral interface
(SPI) or I2C communication interface. It is
designed to work with MPS’s motor drivers that
use a serial interface, as well as the motor
driver programming graphic user interface (GUI)
tool.
The EVKT-MOTOR-00A kit includes one USB
communication device interface, one USB cable,
and one 10-pin ribbon cable. By working with
MPS’s Motor Driver Programming GUI, the
EVKT-MOTOR-00A provides a quick and
simple way to evaluate the performance of MPS
motor drivers with serial interfaces.

QUICK START GUIDE (1)
1. Connect the EVKT-MOTOR-00A to the evaluation board with the 10-pin ribbon cable and ensure
that they are connected.
2. Connect the EVKT-MOTOR-00A to the computer using the supplied USB cable.
3. Turn on the power supply of the evaluation board, then start the motor driver GUI software; the GUI
should check the connections automatically.
a. If USB and device connections are successful, the GUI’s home page should display two green
lights (see Figure 4).
Figure 4: Successful Connection
b. If the USB connection is successful but the device connection is not successful, the GUI’s home
page should display red and green lights (see Figure 5). The light to check the device
connection can be ignored for the MP6605C, MP6605D, MP6605E, MP6606, MPQ6526-AEC1,
and MPQ6527-AEC1.

c. If the USB connection is not successful, the GUI’s home page should display two red lights (see
Figure 6).

4. Select the device, then click “Details”. The configuration register information should be displayed.
Note:
1) It is important to adhere to the order of steps 1 and 2. Failing to do so may cause damage to the communication pins during a hot-plug
event.
