A detailed schematic PDF for the functionally equivalent Adafruit V1 shield can be referenced for troubleshooting or board modification.
The Arduino’s onboard regulator powers both the Arduino board and the motor supply rail. Warning: Only use this configuration for tiny, low-current 5V motors. Running larger motors this way can instantly destroy your Arduino regulator.

The HW-130 Motor Control Shield is a versatile, cost-effective expansion board designed for Arduino UNO and Mega boards. It allows hobbyists, makers, and engineers to safely drive multiple motors simultaneously without risking damage to the Arduino microcontroller.

4.5V to 25V (though some versions specify up to 12V or 16V depending on capacitor ratings). Protection: Internal kickback diodes and thermal shutdown. 5.imimg.com Pinout and Connectivity
When purchasing, confirm that the shield includes the and the 74HC595 shift register – some very cheap clones may omit the shift register and use more I/O pins. Running larger motors this way can instantly destroy
💡 Always use an external power supply for DC motors to avoid crashing your Arduino due to voltage drops.
