Hw 130 Motor Control Shield For Arduino Datasheet 【FHD 2025】

Current warning: Do not exceed 1.2A peak per channel. For 4 motors running simultaneously, total current should stay below 2A to prevent L293D thermal shutdown.

---

The HW-130 is fully compatible with Adafruit’s AFMotor library.

Installation:
Download from Adafruit’s GitHub or via Arduino Library Manager (search “Adafruit Motor Shield”).

Example: Two DC motors

#include <AFMotor.h>
AF_DCMotor motor1(1);  // M1
AF_DCMotor motor2(3);  // M3
void setup() 
motor1.setSpeed(150); // 0-255
motor2.setSpeed(200);
motor1.run(FORWARD);
motor2.run(BACKWARD);

void loop() 
motor1.run(FORWARD);
motor2.run(BACKWARD);
delay(2000);
motor1.run(RELEASE); // stop
motor2.run(RELEASE);
delay(1000);

Stepper motor example:

#include <AFMotor.h>
AF_Stepper stepper(48, 1); // 48 steps per revolution, motor port 1 (M1+M2)
void setup() 
stepper.setSpeed(30); // 30 rpm

void loop() 
stepper.step(100, FORWARD, SINGLE);
delay(1000);
stepper.step(100, BACKWARD, DOUBLE);
delay(1000);

Servo voltage selection – Jumper selects servo VCC from 5V (Arduino) or VS (external).

⚠️ Warning: Do not exceed 12V or 600mA per channel continuously.

// HW 130 with analogWrite() PWM speed control
// Remove the ENA and ENB jumpers from the shield first
int ENA = 3;  // PWM capable
int ENB = 11; // PWM capable hw 130 motor control shield for arduino datasheet
void setup() 
pinMode(4, OUTPUT); // IN1
pinMode(5, OUTPUT); // IN2
pinMode(6, OUTPUT); // IN3
pinMode(7, OUTPUT); // IN4
pinMode(ENA, OUTPUT);
pinMode(ENB, OUTPUT);
// Set direction forward for both motors
digitalWrite(4, HIGH);
digitalWrite(5, LOW);
digitalWrite(6, HIGH);
digitalWrite(7, LOW);

void loop() 
// Ramp up speed from 0 to 255
for (int speed = 0; speed <= 255; speed++) 
analogWrite(ENA, speed);
analogWrite(ENB, speed);
delay(10);
delay(1000);
// Ramp down speed
for (int speed = 255; speed >= 0; speed--) 
analogWrite(ENA, speed);
analogWrite(ENB, speed);
delay(10);
delay(1000);

The HW 130 includes a current sensing circuit: a 0.5Ω resistor and a voltage divider. The output at CS A (Arduino A0) is approximately 0.5V per Ampere.

Formula: Motor Current (A) = (analogRead(A0) * (5.0 / 1023.0)) / 0.5 Current warning: Do not exceed 1

Practical Use: Detect stalls, measure load, or implement torque limiting.

int currentPin = A0;
float voltage, current;
void setup() 
Serial.begin(9600);

void loop() 
// Read current from Motor A
voltage = analogRead(currentPin) * (5.0 / 1023.0);
current = voltage / 0.5; // Because sensor is 0.5V/A
Serial.print("Motor Current: ");
Serial.print(current);
Serial.println(" A");
delay(500);

Located at the bottom edge of the shield:

According to the standard L298P datasheet applied to the HW-130 board:

The HW 130 includes a 78M05 linear voltage regulator. This circuit is critical: The HW-130 is fully compatible with Adafruit’s AFMotor

Warning: Do not connect a 12V battery to Vs while JP1 is open. The 5V line will float, and your Arduino will not get logic power.
