Function

Description

Power Input Terminal

Connect to battery.

● VB+ : Positive

● VB- : Negative

Motor Output Terminal

Connect to motor terminal.

Motor direction depends on the polarity.

Power LED

Turn on when power up.

Motor Status LEDs

Turn on when the motor is running.

● M1A / M2A : Forward*

● M1B / M2B : Backward*

Test Buttons

Press to test the functionality of the motor driver.

Motor will run at full speed.

● M1A / M2A : Forward*

● M1B / M2B : Backward*

Input Signal &

5V Output

Input signal from microcontroller to control the motor.

+5V output can be used to power the microcontroller.

● M1A : PWM Input A for motor 1.

● M1B : PWM Input B for motor 1.

● 5VO : DC +5V Output (Maximum 200mA)

● GND : Ground

● M2A : PWM Input A for motor 2.

● M2B : PWM Input B for motor 2.
