The HW-130 Motor Control Shield is a versatile, budget-friendly expansion board designed for Arduino enthusiasts and robotics builders. Based on the classic L293D dual H-bridge motor driver IC, this shield allows you to control multiple motors simultaneously without a messy tangle of jumper wires.
Note: The HW-130 is a clone/variant of the popular L293D-based motor driver shields (similar to the Arduino Motor Shield Rev3). If you have a specific brand variant, pin functions remain largely the same. Must connect to Arduino GND
Connect your motor power supply (4.5V–25V) to the screw terminals. Pay close attention to polarity (+ and -).
These pins control the speed of the connected DC motors via Pulse Width Modulation (PWM). Digital Pin 11 Motor 2 (M2): Digital Pin 3 Motor 3 (M3): Digital Pin 5 Motor 4 (M4): Digital Pin 6 Powering the HW-130 Shield
