Hw 130 Motor Control Shield For Arduino Datasheet Free Jun 2026

Because the shield uses a 74HCT595 shift register to handle direction controls, it only requires 4 data pins to run 4 DC motors. The breakdown of occupied pins on the Arduino includes: Shift register Clock (CLK) Digital Pin 7: Shift register Enable (EN) Digital Pin 8: Shift register Latch (STRB) Digital Pin 12: Shift register Data input (SER) Speed Control (PWM) Pins: Digital Pin 11: PWM control for Motor 1 (M1) Digital Pin 3: PWM control for Motor 2 (M2) Digital Pin 5: PWM control for Motor 3 (M3) Digital Pin 6: PWM control for Motor 4 (M4) Available/Free Pins

The easiest way to control the HW-130 shield is by using Adafruit's original , which handles the complex shift register matrix coding for you. Installing the Library Open the Arduino IDE.

Used for controlling the two Servo channels. Library Installation hw 130 motor control shield for arduino datasheet

If removed, Arduino power and motor power are separated. If installed, the motor power source can power the Arduino. 4. How to Use the HW-130 with Arduino
