Shield For Arduino Datasheet Better | Hw 130 Motor Control

The HW-130 Motor Control Shield (often identified as the L293D Motor Driver Shield) is one of the most popular and versatile expansion boards for the Arduino Uno and Mega. Designed to handle the high current demands that microcontroller pins cannot support directly, it simplifies complex robotics projects by managing up to four DC motors or two stepper motors simultaneously. Key Technical Specifications

6. Stepper Motor (Unipolar/Bipolar)

You can drive a small bipolar stepper (e.g., 28BYJ-48 as bipolar mod) or a unipolar stepper. hw 130 motor control shield for arduino datasheet better

• The Big Chip(s): Look for the large black chips labeled L293D. This is the heart of the shield. It is a quadruple high-current half-H driver.
• The Shift Register: Look for a smaller chip, usually labeled 74HC595. This is a shift register.

5. Logic Control Truth Table

To make the motor move, you send HIGH or LOW signals to the IN pins. The HW-130 Motor Control Shield (often identified as
