Hw 130 Motor Control Shield For Arduino Datasheet (2027)

Uses a 74HC595 shift register to expand 3 Arduino pins into 8 direction control pins. Key Features & Design

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.

If the "PWR" jumper is connected, the shield draws power from the Arduino. For high-torque motors, remove the jumper and use the EXT_PWR terminals. hw 130 motor control shield for arduino datasheet

Whether you are building a first robot, a CNC machine, or an automated home system, the HW-130 offers a robust, well‑documented solution. By following the power supply rules and using the widely supported AFMotor library, you can have your project moving in minutes.

To preserve pins for external sensors, the shield does not use a direct pin-per-motor arrangement. Instead, the 74HC595 shift register handles direction inputs (forward/reverse), requiring only 3 digital pins for control.

The HW 130 includes a 78M05 linear voltage regulator. This circuit is critical:

| Feature | HW-130 (L293D) | L298N Shield | TB6612 Shield | |-----------------------|------------------------|--------------------|---------------------| | Max current | 0.6A continuous | 2A | 1.2A | | Voltage range | 4.5–12V | 5–24V | 4.5–13.5V | | PWM frequency noise | Audible (~1kHz) | Lower | Ultrasonic (high) | | Efficiency | Poor (linear-like) | Moderate | Good | | Price | Very low (~$5) | Low (~$8) | Moderate (~$12) |

For beginners or educators, the HW-130 works with , a visual programming environment for Arduino. You can drag and drop blocks to control motors without writing code. The AFMotor library must still be included in a global “insert code” block.
