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
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. hw 130 motor control shield for arduino datasheet
