The HW-130 Motor Control Shield is suitable for a wide range of applications that require motor control, including:
(Note: On some generic variations of this board, the Direction and Speed pins may be swapped (e.g., D5/D6 for speed), but the D3/D11/D12/D13 configuration is standard for the L298P Shield design.)
