The HW-130 motor control shield is a popular, budget-friendly expansion board for Arduino. It allows you to drive multiple DC motors, stepper motors, and servos simultaneously. This guide serves as an extended datasheet and technical manual to help you get your robotics projects up and running. Technical Specifications

The HW-130 shield offers a simple, inexpensive solution for driving small DC motors (e.g., toy motors, mini fans, small robots) from an Arduino Uno. While lacking advanced features like current sensing or external flyback diodes, it is suitable for educational projects and low-power applications. Users must respect the 1.2A peak limit and provide an appropriate external motor power supply for reliable operation.
