Hw 130 Motor Control Shield For Arduino Datasheet Site

According to various technical datasheets for this hardware revision: Adafruit Motor Shield

Understanding how the HW-130 maps its pins is essential, as it uses the 74HC595 shift register to handle direction controls over a serial link, freeing up crucial hardware PWM pins on your Arduino. Dedicated Hardware Pins

A small button to reset the Arduino without removing the shield. 4. Pinout and Usage hw 130 motor control shield for arduino datasheet

Looking at the HW-130 PCB, you'll see a small jumper labeled (Enable).

void setup() stepper1.setSpeed(30); // 30 rpm stepper1.step(100, FORWARD, SINGLE); According to various technical datasheets for this hardware

The shield simplifies wiring by plugging directly onto the Arduino . It uses a shift register to control motor directions, meaning only a few digital pins are occupied .

It is a cost-effective alternative to official shields, especially popular among hobbyists and educators building small robots, automated systems, and various motion-control projects. Pinout and Usage Looking at the HW-130 PCB,

: The library also supports MOTOR12_64KHZ and MOTOR34_64KHZ PWM frequency modifiers for quieter motor operation.

Connect Coil A to M1 (or M3) and Coil B to M2 (or M4). The center tap (if using a 5-wire/6-wire unipolar stepper) connects to the ground (GND) pin between the terminals. SER1 & SER2: 3-pin male headers for standard 5V RC servos. Pins Utilized by the Shield
