The HW-130 serves as a high-density power interface between the low-current logic of an Arduino microcontroller and high-current inductive loads. Go to product viewer dialog for this item. Arduino Motor Shield Rev3
The HW-130 Motor Control Shield is a DC motor driver shield specifically designed for Arduino Uno, Arduino Mega, and other compatible boards. It provides a simple and efficient way to control two DC motors, making it ideal for robotics, automation, and other applications that require motor control.
9V batteries have very high internal resistance and low capacity. They cannot supply the current spikes motors need, leading to poor performance and fast battery drain. hw 130 motor control shield for arduino datasheet better

If you use analogWrite() on pins 9, 10, 5, or 6, the PWM frequency is ~490Hz or ~980Hz depending on the board. The L298N works best below 25kHz, so this is fine—but the shield’s response becomes nonlinear below 30% duty cycle due to the H-bridge dead-time. A better datasheet would warn you.
The is a low-cost, clone variant of the popular L293D-based motor shield (similar to the Adafruit or DFRobot designs). It is designed to drive: The HW-130 serves as a high-density power interface
