This shield utilizes specific Arduino pins to control direction and speed (PWM). Note that when this shield is attached, you cannot use these pins for other sensors.
Completely separates logic power (Arduino) from motor power (EXT_PWR terminal) [1]. Highly recommended to prevent damage to your Arduino [1]. Occupied Arduino Pins
The HW-130 motor control shield is a popular, budget-friendly expansion board for Arduino. It allows you to control multiple DC motors, stepper motors, and servos simultaneously. This guide serves as a comprehensive datasheet and technical manual to help you integrate the HW-130 into your robotics and automation projects. Technical Specifications
Screw terminal blocks to connect DC motors or stepper motors [1].
Used for Pulse Width Modulation (PWM) to control motor speed.
Connect your battery to the VIN terminal on the shield. Ensure polarity is correct ( −negative Power Selection: Keep the PWR jumper on if your battery is 12V12 cap V Example Code (Speed and Direction Control)
#include <AFMotor.h>
Connect the Arduino to its own power supply (USB or DC jack).
PWM Speed Control & Digital Direction Control. Compatibility: Directly stacks onto Arduino UNO/Mega. HW-130 Motor Control Shield Datasheet Breakdown (Free)
2 connections for 5V hobby servos using the Arduino's high-resolution timers. Current Output: 600mA continuous per channel (1.2A peak).
600 mA continuous per channel (1.2A peak current) [1]
Plug the Arduino USB cable into your computer to upload code and supply logic power [1]. 💻 Arduino Code Example
AF_Stepper stepper(200, 1); // 200 steps/revolution, motor port #1
void setup() stepper.setSpeed(30); // 30 rpm
Remove the physical plastic jumper pin next to the external power terminal block [1].
