Function

Description

PWM/DIR Input

Control the motor with PWM/DIR signal.

● PWM : PWM input for motor speed control.

● DIR : Direction input.

● 5VO : 5V Output. Can be used to power Arduino and other

MCU.

● GND : Signal ground.

Speed Control

Potentiometer

Connect to 10KΩ potentiometer for motor speed control.

● POT 1 (GND) : Connect to pin 1 of the pot (Lowest speed).

● POT 2 (Analog In) : Connect to pin 2 of the pot (Middle pin).

● POT 3 (5V) : Connect to pin 3 of the pot (Highest speed).

Direction Switch

Connect to SPDT Switch for motor direction control.

MA and MB are internally pulled high.

● MA : Short to GND to run forward*.

● COM : Common pin. Connected to GND internally.

● MB : Short to GND to run backward*.

∗

Actual motor direction is depending on the motor connection.

Swapping the connection (MA & MB) will reverse the direction.
