Note: The HW-130 is a clone/variant of the popular L293D-based motor driver shields (similar to the Arduino Motor Shield Rev3). If you have a specific brand variant, pin functions remain largely the same.

HW-130 Motor Control Shield (often marketed as the L293D Motor Driver Shield) is a versatile, entry-level expansion board for Arduino designed to simplify the complex task of driving inductive loads like DC motors, steppers, and servos. Based on the classic Adafruit Motor Shield V1 design, it centralizes motor control by consolidating multiple H-bridges and shift registers into a single "plug-and-play" footprint.

⚠️ The specific pin mapping can vary slightly between clones. However, the shield is almost universally compatible with the Adafruit Motor Shield V1 library ( AFMotor.h ), which handles these pin definitions automatically.
When purchasing, confirm that the shield includes the and the 74HC595 shift register – some very cheap clones may omit the shift register and use more I/O pins. Note: The HW-130 is a clone/variant of the
The datasheet implies "Standard Arduino Logic." Here is the translation:
The Arduino and the motors share the same power source. Power supplied via the Arduino's DC jack will also power the motors. Only use this for very small, low-current motors. Based on the classic Adafruit Motor Shield V1
The shield uses a shift register to control the direction of the DC/Stepper motors. This saves precious Arduino pins. Shift Clock Digital Pin 7: Register Clock / Latch Digital Pin 8: Serial Data Input Digital Pin 12: Output Enable 3. PWM Speed Control Pins
