Hw - 130 Motor Control Shield For Arduino Datasheet Better High Quality

The L298N’s thermal shutdown occurs at 70°C junction temp. On the HW-130, the heatsink is glued poorly, and airflow is blocked by the Arduino below. You will hit thermal rollback at 1.8A continuous in a 25°C room.

Here is a simple example to run a motor back and forth.

The most significant difference is that the , while an L298N can supply over 2A. For small robots with small motors, the HW-130 is ideal. For anything larger, an L298N or a more powerful shield is necessary.

Separate power input for motors to protect the Arduino. 2. Technical Specifications & Datasheet Data Driver IC: 2 × L293D (Quadruple Half-H Drivers). hw 130 motor control shield for arduino datasheet better

// Set the initial speed of the motor (values 0-255) motor1.setSpeed(150);

Uses a 74HC595 serial-to-parallel converter to save Arduino pins. 4. Power Management (Crucial Step) The motors require more power than the Arduino can provide.

The shield uses pins 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12. You cannot use these for sensors. The L298N’s thermal shutdown occurs at 70°C junction temp

Do not ignore the . The HW-130 includes 1N4007 diodes on board, but those are too slow for PWM. Better upgrade: solder 1N5819 Schottky diodes across OUT1-2 and OUT3-4 (cathode to positive supply, anode to output).

A: The most common reason is insufficient voltage or current from your power supply. Ensure your battery pack is fully charged and capable of delivering the required current. You can also try increasing the speed in your code beyond 150 to 255.

A: They are functionally almost identical. Both are based on the L293D IC. The official Arduino shield may have slightly better build quality and component layout, but the HW-130 is a much more affordable clone. Here is a simple example to run a motor back and forth

If you’ve ever searched for you have likely landed on a handful of cryptic Chinese PDFs, low-resolution pinout diagrams, or forum posts with conflicting wiring instructions. You are not alone. The HW-130 is one of the most popular—yet poorly documented—dual motor driver shields on the market.

The (often referred to as the L293D Motor Shield) is a popular, low-cost driver for small motors. It is based on two L293D motor driver ICs and a 74HC595 shift register to minimize the number of Arduino pins used. Key Specifications
