Operation of the EVM

Use the steps that follow for operating the EVM:

Step 1.

Connect a brushed DC motor to header JP3.

Step 2.

Turn the speed-adjust potentiometer R7 all the way to the left so that the arrow points to 0%.

Step 3.

Connect the positive terminal of the power supply to the JP2 header lead labeled VM.
Connect the negative terminal of the power supply to the JP2 header lead labeled GND.

Step 4.

Install the JP1 jumper.

Step 5.

Turn on the power supply. The D1 LED labeled STATUS should start blinking.

Step 6.

Slowly turn the R7 potentiometer to the right towards the 100% label until the motor begins
spinning.

Step 7.

To change direction either install or remove the JP4 jumper.

WARNING

Hot surface. Contact may cause burns. Do not touch.
