Introduction

2.5 Motor Outputs

Connect a DC motor across O1 and GND. If desired, connect an additional DC motor across O2 and

GND. To reverse motor direction, connect the motor across O1 and VM or O2 and VM.

2.6 Operation of the EVM

Use the following steps to operate the EVM:

1. Connect the included DC motor across O1 and GND. If desired, connect an additional DC motor

across O2 and GND.

2. Adjust the potentiometer, R2, to minimum voltage by turning the wheel clockwise all the way. This

minimizes the motor speed.

3. Apply power to J3 header or with external USB cable plugged into a computer USB jack.

4. Turn potentiometer, R2, counter-clockwise and the motor will start to turn. Continue adjusting, as

desired, until you reach maximum speed.
