5.2 Wiring Diagram

Refer to the following diagram for proper connection of power, motor, and control signals.

Wiring diagram for the GODIYMODULES Motor Driver Module, showing connections for power, motor, and input signals. — Figure 4: Wiring Diagram. This diagram illustrates how to connect the power supply (Power+ and Power-), the motor, and the control inputs (Input 1 and Input 2) to the module. Ensure correct polarity for power connections.

5.3 Connection Steps

Power Supply Connection: Connect your DC power supply (5V to 15V) to the "MOTOR-PWR+" terminal block. Ensure the positive (+) terminal of the power supply connects to the "+" screw terminal and the negative (-) terminal connects to the "-" screw terminal.
Motor Connection: Connect your DC motor to the "MOTOR" screw terminals. The polarity here will determine the initial direction of rotation.
Control Signal Connection: Connect your microcontroller or control source to the input pins:
- IN1: Input 1 for controlling motor direction/speed.
- IN2: Input 2 for controlling motor direction/speed.
- GND: Ground connection for the control signals, typically connected to the microcontroller's ground.
Verify Connections: Double-check all connections for correct polarity and secure fastening before applying power.

6. Operating Instructions

The module uses two input signals (IN1 and IN2) to control the motor's direction and speed via PWM. The power indicator LED will illuminate when power is supplied to the module.

6.1 Motor Control Logic

IN1 Signal	IN2 Signal	Motor Action
LOW (0V)	LOW (0V)	Motor Stop (Brake)
HIGH (3.3V-12V)	LOW (0V)	Motor Forward (Speed controlled by PWM on IN1)
LOW (0V)	HIGH (3.3V-12V)	Motor Reverse (Speed controlled by PWM on IN2)
HIGH (3.3V-12V)	HIGH (3.3V-12V)	Motor Stop (Brake)

To control motor speed, apply a Pulse Width Modulation (PWM) signal to the active input (IN1 for forward, IN2 for reverse). The frequency of the PWM signal can be up to 200kHz.

The module is designed with signal isolation to protect the microcontroller from motor noise and voltage spikes.

7. Maintenance

The GODIYMODULES Motor Driver Module requires minimal maintenance. Follow these guidelines to ensure longevity and reliable operation:

Keep Clean: Ensure the module is free from dust, dirt, and moisture. Use a soft, dry brush or compressed air for cleaning.
Environmental Conditions: Operate the module within its specified temperature and humidity ranges. Avoid extreme conditions.
Heat Management: For applications involving high continuous currents, ensure adequate airflow around the heatsinks to prevent overheating. Consider additional cooling if necessary.
Connection Integrity: Periodically check all screw terminal connections to ensure they are tight and secure. Loose connections can lead to intermittent operation or arcing.

8. Troubleshooting

If you encounter issues with your motor driver module, refer to the following troubleshooting steps:

Problem	Possible Cause	Solution
Module not powering on (Power LED off)	No power supply, incorrect polarity, faulty power supply, loose connections.	Verify power supply is connected and providing 5V-15V DC. Check power supply polarity (+ to +, - to -). Ensure all power connections are secure. Test power supply with a multimeter.
Motor does not move	Incorrect control signals, motor not connected, faulty motor, insufficient power, module damage.	Check IN1/IN2 signals according to the control logic table. Ensure motor is correctly wired to the "MOTOR" terminals. Verify motor functionality by connecting it directly to a power source (briefly). Confirm power supply can deliver sufficient current for the motor. Check for any visible damage on the module.
Motor moves in wrong direction	Incorrect IN1/IN2 signal combination, motor polarity reversed.	Adjust IN1/IN2 signals as per the control logic table for desired direction. Reverse the motor connections at the "MOTOR" terminals if necessary.
Module gets excessively hot	Overcurrent, insufficient heat dissipation, short circuit.	Reduce motor load or operating current. Ensure adequate ventilation around the heatsinks. Check for any short circuits in the motor or wiring. Verify the motor's current draw does not exceed the module's continuous rating.
