Shield For Arduino Datasheet: Hw 130 Motor Control

For any serious project with motors exceeding 700 mA, consider upgrading to a MOSFET-based shield, but for light robotics and classroom work, the HW-130 remains a reliable workhorse. Document version 1.0 – Last updated: April 2026 This datasheet is based on reverse engineering of the HW-130 hardware and public L293D documentation.

void setup() stepper.setSpeed(30); // 30 rpm

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

#include <AFMotor.h> AF_DCMotor motor1(1); // M1 AF_DCMotor motor2(3); // M3 For any serious project with motors exceeding 700

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

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

Approx. 4W (with proper cooling) 3. Pinout & Hardware Layout The HW-130 sits directly on top of the Arduino Uno. It uses the following Arduino digital and analog pins (note that analog pins A0–A5 are broken out for general use ): Dedicated Motor Pins: | Motor | Direction Pin (Arduino) | PWM Speed Pin (Arduino) | |-------|------------------------|-------------------------| | M1 | D12 | D5 | | M2 | D11 | D6 | | M3 | D8 | D9 | | M4 | D7 | D10 |
