Hw 130 Motor Control Shield For Arduino Datasheet Better ●

HW-130 Motor Control Shield is a popular clone of the original Adafruit Motor Shield v1 . It is designed for plug-and-play use with Arduino Uno

• 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.

• Input Voltage: 5V to 35V
• Output Current: 2A per channel
• Peak Output Current: 4A per channel
• Motor Type: DC motors, stepper motors
• Control Interface: Arduino compatible
• Protection: Overcurrent, overvoltage, thermal shutdown
• Dimensions: 53mm x 57mm x 23mm

void loop() // --- Move Forward (Half Speed) --- digitalWrite(IN1, HIGH); digitalWrite(IN2, LOW); analogWrite(ENA, 150); // Speed (0-255)

When to upgrade:

Typical wiring diagrams

• Verify VIN and GND are connected and voltage present.
• Confirm Arduino pins match shield wiring and are set as outputs.
• Check PWM value >0 and DIR pin state correct.

• Servo 1: Connected to Arduino Digital Pin 10.
• Servo 2: Connected to Arduino Digital Pin 9.
