Hw 130 Motor Control Shield For Arduino Datasheet Better May 2026

There are usually jumpers near the power terminals.

Jumper OFF: Separates motor power from Arduino power.

Always use separate power for motors and logic. Remove the 5V jumper and feed 5V from a reliable source (or Arduino’s 5V pin if current <200mA). This prevents back-EMF from resetting your Arduino.

The shield breaks out two headers specifically for servos. These bypass the motor driver chips entirely.

The HW-130 is a functional but fragile L293D-based motor shield. To use it successfully:

For a “better” shield with datasheet support, consider the L298N (2A per channel) or TB6612FNG (1.2A, efficient). However, the HW-130 remains a valid entry-level choice for educational robot cars.

This paper replaces the missing manufacturer datasheet. Always verify pin continuity on your specific clone board before connecting motors.

HW-130 Motor Control Shield (often referred to as the L293D V1 Motor Shield) is a versatile expansion board for the Arduino Uno and Mega. It acts as a bridge, allowing the low-power signals from your Arduino to control high-power motors without damaging the microcontroller. Technical Specifications The core of this shield consists of two L293D dual-channel H-bridge drivers 74HC595 shift register to manage I/O pins efficiently. Motor Capacity 4 DC motors with individual 8-bit speed selection. 2 stepper motors (unipolar or bipolar). 2 "hobby" servos (5V) connected to dedicated high-resolution timers. Power Ratings : Supports motors between 4.5V and 25V : Provides 600mA per channel (1.2A peak) with thermal shutdown protection. Safety Features

: Pull-down resistors ensure motors stay disabled during Arduino power-up to prevent erratic movement. 5.imimg.com Pinout and Control Logic hw 130 motor control shield for arduino datasheet better

The HW-130 motor control shield for Arduino is a widely used, budget-friendly motor driver based on the classic L293D chipset. Often referred to as a clone of the original Adafruit Motor Shield (v1), it is designed to stack directly onto an Arduino Uno or Mega, providing a compact solution for driving multiple motors without messy breadboard wiring. Key Technical Specifications

The HW-130 uses two L293D dual H-bridge chips and one 74HC595 shift register to expand the available control pins. L293D Based Arduino Motor Shield

Here is the "deep story" datasheet and technical breakdown you need to get the most out of this hardware.

The L298N chip loses ~1.5V to 2V under load. If you feed it 6V, your motor sees only ~4.5V. For full performance, use 9V or 12V batteries. Jumper OFF: Separates motor power from Arduino power
