The shield uses a shift register (74HCT595) to save Arduino pins, requiring only 3 digital pins to control 4 DC motors. Arduino Pin(s) Used Digital Pin 9 Uses Timer 1 (Uno) or Timer 2 (Mega) Servo 2 Digital Pin 10 Uses Timer 1 DC Motor 1 / Stepper 1 Digital Pin 11 PWM for speed control DC Motor 2 / Stepper 1 Digital Pin 3 PWM for speed control DC Motor 3 / Stepper 2 Digital Pin 5 PWM for speed control DC Motor 4 / Stepper 2 Digital Pin 6 PWM for speed control Shift Register Control Digital Pins 4, 7, 8, 12 Used for direction control of all motors Powering Your Motors The HW-130 features a PWR Jumper . L293D Based Arduino Motor Shield
Standard L298N modules have physical jumpers for ENA and ENB. On the HW-130 Shield, these are often connected to specific Arduino pins. hw 130 motor control shield for arduino datasheet better
