The HW-130 features a dedicated terminal for external power. Because Arduino pins cannot provide enough current for motors, you should connect an external battery pack (typically 6V–12V) to the terminals.

Comprehensive Guide to the HW-130 Motor Control Shield for Arduino

The shield uses almost all digital pins on the Arduino Uno, which is a critical detail for planning your project. Arduino Pins Used Digital 9 and 10 DC/Stepper Motors Digital 3, 5, 6, 11 (PWM) Shift Register (74HC595) Digital 4, 7, 8, 12

These are the screw terminals for DC motors. Stepper 1: Uses M1 and M2. Stepper 2: Uses M3 and M4.
