Hw 130 Motor Control Shield For Arduino Datasheet Better -

is one of the most versatile, cost-effective multi-motor driver expansions available for the and Arduino Mega ecosystem . Based on the classic open-source Adafruit Motor Shield v1 design , the HW-130 integrates two L293D Dual H-Bridge motor driver ICs alongside a 74HC595 shift register . This specific hardware arrangement allows makers to control up to 4 bidirectional DC motors, 2 stepper motors, and 2 hobby servos simultaneously, using only a tiny fraction of the Arduino's digital I/O pins.

// Linearization: map 0-255 to 30-255 to avoid dead zone speed = map(speed, 0, 255, 30, 255); analogWrite(ENA, constrain(speed, 0, 255));

: Pull-down resistors ensure motors stay disabled during Arduino power-up to prevent erratic movement. 5.imimg.com Pinout and Control Logic

Note: Pin assignments can vary slightly depending on the specific clone manufacturer, but these are standard for the Adafruit-derived designs. hw 130 motor control shield for arduino datasheet better

// --- Stop --- digitalWrite(IN1, LOW); digitalWrite(IN2, LOW); delay(1000);

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

Up to 4 bi-directional DC motors, 2 stepper motors (unipolar/bipolar), or 2 servo motors. Operating Voltage: 4.5V to 16V for motors (logic requires 5V). Current Handling: is one of the most versatile, cost-effective multi-motor

This means the HW-130 is designed for small to medium-sized DC motors, not for heavy-duty industrial motors. Exceeding these current limits can cause erratic behavior or damage the chip.

The HW-130 routes the L298N pins to specific Arduino pins. This is the critical reference for your code.

The datasheet never mentions this, but the shield works fine for light stepper loads (NEMA 17 size max). // Linearization: map 0-255 to 30-255 to avoid

The is one of the most widely used, budget-friendly motor driver expansion boards available for hobby robotics. Based on the classic open-source design of the Adafruit Motor Shield V1, this board provides an easy way to drive combinations of DC motors, stepper motors, and hobby servos directly from an Arduino UNO or Mega.

Because original manufacturer documentation for clone modules can be fragmented, this document serves as a complete, consolidated datasheet and deployment guide. It delivers better, clearer technical definitions, accurate pin mappings, and concrete implementation examples to maximize the performance of your robotics hardware. 1. Core Technical Specifications
