All Rights Reserved. 5 EVKT6532 DEMO BOARD QUICK START GUIDE To quickly start using the EVKT6532 BLDC motor driver board, do the following: 1. Connect the U, V, and W wires of a BLDC motor to MOTOR connector. Connect the motor Hall sensors to the HALL connector. 2. Connect a power supply (between 5V and 60V) to the VIN and GND pins. 3. Slide the DIR switch to “FWD” or “REV” to control the direction of the motor. Slide the “RUN/STOP” switch to the right to run the motor. Slide the “BRAKE” switch to the right to apply short braking to the motor. 4. Adjust the motor speed by turning the SPEED pot. Note: Please pay attention to the correct input polarity connection, to avoid damage due to reversed connection. NOTICE: The information in this document is subject to change without notice.
