Hw 130 Motor Control Shield For: Arduino Datasheet

These are the screw terminals for DC motors. Stepper 1: Uses M1 and M2. Stepper 2: Uses M3 and M4.

The HW-130 Motor Control Shield is an essential "bridge" for robotics. While it uses an older L293D architecture, its ease of use and compatibility with the Adafruit library make it the go-to choice for students and hobbyists building their first motorized creations. hw 130 motor control shield for arduino datasheet

If the jumper is shorted, the Arduino and the motors share the same power source. It is highly recommended to remove the jumper and use separate power supplies to avoid resetting the Arduino due to voltage spikes. Motor Connections

This happens when motors draw too much current from the Arduino's 5V rail. Always use external power for the shield. These are the screw terminals for DC motors

Check the PWR jumper. If it's off and you haven't connected external power to the shield, the motors won't move even if the Arduino is on.

The (often referred to interchangeably with the L293D Motor Drive Shield) is one of the most versatile and affordable tools for hobbyists looking to add motion to their Arduino projects. Whether you are building a four-wheel-drive robot, a pan-tilt camera system, or a basic CNC machine, this shield provides the necessary power handling to bridge the gap between delicate microcontrollers and power-hungry motors. 74HC595 (Used to expand pins for motor control)

The HW-130 features a dedicated terminal for external power. Because Arduino pins cannot provide enough current for motors, you should connect an external battery pack (typically 6V–12V) to the terminals.

This datasheet and guide will cover the specifications, pinouts, and practical usage of the HW-130. 1. Technical Specifications

The shield uses almost all digital pins on the Arduino Uno, which is a critical detail for planning your project. Arduino Pins Used Digital 9 and 10 DC/Stepper Motors Digital 3, 5, 6, 11 (PWM) Shift Register (74HC595) Digital 4, 7, 8, 12
