Datasheet

If using a Breakout:

Connect the driver board and servo as shown on the previous page. Don't forget to provide power to both Vin (3-5V

logic level) and V+ (5V servo power). Check the green LED is lit!

If using a Shield:

Plug the shield into your Arduino. Don't forget you will also have to provide 5V to the V+ terminal block. Both red and

green LEDs must be lit.

If using a FeatherWing:

Plug the FeatherWing into your Feather. Don't forget you will also have to provide 5V to the V+ terminal block. Check

the green LED is lit!

Connect a Servo

A single servo should be plugged into the PWM #0 port, the first port. You should see the servo sweep back and forth

over approximately 180 degrees.

Calibrating your Servos

Servo pulse timing varies between different brands and models. Since it is an analog control circuit, there is often

some variation between samples of the same brand and model. For precise position control, you will want to calibrate

the minumum and maximum pulse-widths in your code to match known positions of the servo.

Find the Minimum:

Using the example code, edit SERVOMIN until the low-point of the sweep reaches the minimum range of travel. It is

best to approach this gradually and stop before the physical limit of travel is reached.

Find the Maximum:
