Hw 130 Motor Control Shield For Arduino Datasheet File

The HW-130 is a popular L293D-based motor driver shield. It is designed to plug directly onto an Arduino Uno or Mega to control multiple motors simultaneously. Key Specifications Two L293D Push-Pull Drivers. Motor Capacity: 4 Bi-directional DC motors (8-bit speed resolution). 2 Stepper motors (unipolar or bipolar). 2 Servo motors (connected to Arduino’s high-res timers).

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.

Looking at the HW-130 PCB, you'll see a small jumper labeled (Enable).

For sourcing, search for "HW-130 L293D Motor Shield" or the original "Adafruit Motor Shield V1". Always refer to the Adafruit library documentation for code updates and advanced features.

A simple application is controlling a 12V computer fan’s speed and direction. The L293D can handle up to 600 mA continuously, which is sufficient for most small cooling fans.

The HW-130 shield is designed to be stacked directly on top of an Arduino Uno or Mega. The following Arduino pins are used by the shield and should not be used for other purposes. The HW-130 is a popular L293D-based motor driver shield

Summary

⚠️ 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.

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.
