when using an external motor supply higher than 12V or when the Arduino is powered via USB to avoid hardware damage. Arduino sketch to test a DC motor or stepper with this shield? Go to product viewer dialog for this item. L293D Motor Driver Shield Board
The HW-130 shield offers a simple, inexpensive solution for driving small DC motors (e.g., toy motors, mini fans, small robots) from an Arduino Uno. While lacking advanced features like current sensing or external flyback diodes, it is suitable for educational projects and low-power applications. Users must respect the 1.2A peak limit and provide an appropriate external motor power supply for reliable operation. hw 130 motor control shield for arduino datasheet free
However, the specific pin mapping isn't always obvious if you don't have the schematic. If you are looking for the official , I’ve uploaded a free copy for reference. when using an external motor supply higher than
