The is a popular multi-H-bridge expansion board for Arduino, based on the L293D chipset. It is designed to drive multiple inductive loads—such as DC motors, stepper motors, and servos—independently using a minimal number of Arduino pins thanks to an onboard shift register. Core Technical Specifications
These connect to your DC motors or stepper motors. M1 and M2 form one block; M3 and M4 form the second block.
Troubleshooting tips
void setup() motor1.setSpeed(150); // 0-255 motor2.setSpeed(200); motor1.run(FORWARD); motor2.run(BACKWARD); hw 130 motor control shield for arduino datasheet
The shield has a jumper that connects the motor supply voltage to the Arduino’s 5V regulator input (Vin).
This article acts as a comprehensive technical datasheet and guide for the HW-130 shield, covering specifications, pinouts, and usage examples.
The HW-130 is a clone/derivative of the classic dual H-bridge driver. However, unlike the big blue heatsink modules, the HW-130 is designed as a shield that stacks directly onto an Arduino Uno or Leonardo. The is a popular multi-H-bridge expansion board for
3-pin header mapped directly to Arduino Digital Pin 10.
void loop() servo1.write(90); servo2.write(45); delay(1000);
This shield is widely recognized for its versatility in small-to-medium robotics projects due to its ability to control multiple motor types simultaneously. L293D Based Arduino Motor Shield M1 and M2 form one block; M3 and M4 form the second block
To easily control the HW-130 shield, you should install the .

The (often referred to interchangeably with the L293D Motor Drive Shield) is one of the most versatile and affordable tools for hobbyists looking to add motion to their Arduino projects. Whether you are building a four-wheel-drive robot, a pan-tilt camera system, or a basic CNC machine, this shield provides the necessary power handling to bridge the gap between delicate microcontrollers and power-hungry motors.
Here’s a concise review of the based on typical user documentation and datasheet content available for this popular low-cost Arduino shield.
