Hw 130 Motor Control Shield For Arduino Datasheet Better Jun 2026

The HW-130's compact design is one of its best features, keeping wiring clean and simple.

Up to with 8-bit speed selection. Up to 2 stepper motors (unipolar or bipolar).

While it's possible to power a small motor from the Arduino's 5V pin during initial testing, this is not recommended. Motors draw significant current, which can cause your Arduino to brown out or reset. Always connect a separate battery pack (4.8V to 24V) to the EXT_PWR terminal.

Despite newer motor drivers being available, the L293D-based HW-130 shield remains a popular choice, especially for those new to electronics. Here are the key reasons why: hw 130 motor control shield for arduino datasheet better

Understanding the pinout is crucial for efficient programming. The HW-130 uses the , mapping its functions to specific pins.

How to Use the HW-130 Motor Shield (Better Approach) A. Powering the Shield

A common problem is leaving the PWR jumper on while powering the shield from a battery and the Arduino from a laptop's USB port. This creates a "power loop" that can potentially damage your computer's USB port.

: 600mA constant current per bridge (1.2A peak). Voltage Range : Supports motor voltages from 4.5V to 12V . The HW-130's compact design is one of its

Check the EXT_PWR terminal polarity. Ensure the PWR jumper is configured correctly.

The HW-130 Motor Control Shield is a popular and highly sought-after accessory for Arduino enthusiasts and robotics professionals alike. This shield is designed to provide a convenient and efficient way to control DC motors, stepper motors, and other loads using an Arduino microcontroller. In this article, we will provide an in-depth review of the HW-130 Motor Control Shield, including its features, technical specifications, and benefits. While it's possible to power a small motor

Proper powering is critical to avoid damaging your Arduino or the shield:

: Thermal shutdown protection and internal kickback protection diodes. Hardware Layout & Pin Mapping

The easiest way to control the HW-130 is by using the Adafruit Motor Shield library .

L293D drivers have an internal voltage drop of roughly 1.5V-2V. A 9V input will only give about 7.5V at the motors.
