• Educational kits – teach H-bridge operation, PWM speed control and motor behavior
• Stepper motor control – run small bipolar steppers using appropriate stepping logic

Getting Started – Basic Hookup Guide

Follow these steps for a safe basic connection:

1. Connect the motor power supply to the motor Vcc screw terminal and ground to GND.
2. If using the onboard regulator, enable the 5V logic supply; otherwise provide a separate 5V logic supply to Vcc logic.
3. Wire motors to the output screw terminals (Motor A and Motor B).
4. Use IN1-IN4 pins to set motor direction. Use ENA and ENB with PWM signals from your microcontroller to control speed.
5. Include decoupling capacitors and ensure the power supply can handle motor stall currents and peaks.

Recommended Wiring Notes

• Use short, thick wires for motor power to reduce voltage drop.
• Place capacitors near the motor supply terminals to reduce noise and voltage spikes.
• Consider adding external flyback diodes or use motors with suppression to protect logic from noise.

Performance Tips

• Use a power supply rated above the motor stall current and provide headroom for peak draws.
• Improve cooling with additional heat sinks or fans for prolonged high-current operation.
• Test PWM frequency and duty cycle to find balance between smooth motor response and heat generation.
• Ensure proper grounding between the driver and microcontroller to avoid signal errors.
