While HW‑130 is a generic clone, its electrical behaviour is identical to the Adafruit Motor Shield V1 and the L293D datasheet. For pin‑level details, refer to the Texas Instruments L293D datasheet . The shift register (74HC595) datasheet is also widely available. The combination of these two ICs defines the shield’s capabilities.
Based on the pinout above, here is the truth table. To spin a motor, you set one direction pin HIGH and the other LOW . To brake, set both HIGH .
If the "PWR" jumper is connected, the shield draws power from the Arduino. For high-torque motors, remove the jumper and use the EXT_PWR terminals. hw 130 motor control shield for arduino datasheet

The HW-130 is a stackable, plug-and-play shield that fits directly onto an Arduino Uno, Mega, or Leonardo. It removes the need for complex breadboard wiring when managing high-power motors.

The HW-130 shield is electrically compatible with the , so the AFMotor library works directly.
Proper power isolation is critical when working with inductive loads like motors to prevent the Arduino from resetting or burning out due to voltage spikes. The Power Jumper (PWR) Functionality
