The HW-130 Motor Control Shield 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
The HW-130 is essentially a "clone" or derivative of the original Adafruit Motor Shield (v1). Its primary hardware components include two L293D motor driver ICs and one 74HC595 shift register. Feature Specification Driver Chip 2 x L293D H-Bridge Drivers Logic Chip 74HC595 8-bit Shift Register Motor Voltage 4.5V to 25V (Standard) / up to 36V (Maximum) Output Current 600mA continuous per channel (1.2A peak) Dimensions ~69mm x 53mm x 14.3mm Key Features and Capabilities L293D Based Arduino Motor Shield hw 130 motor control shield for arduino datasheet
EXT_PWR and GND.Current warning: Do not exceed 1.2A peak per channel. For 4 motors running simultaneously, total current should stay below 2A to prevent L293D thermal shutdown. The HW-130 Motor Control Shield is a popular
