| Problem | Likely Cause | Fix (From HW 130 Schematic) | | :--- | :--- | :--- | | Motors twitch, don't spin | Insufficient motor power supply | VS terminal must provide >5V. For 3.7V toy motors, bypass VS and use Arduino 5V (not recommended). | | Arduino resets when motor starts | Inrush current | Add 470uF–1000uF capacitor across VS and GND on the terminal block. | | Servos jitter | 5V jumper closed, drawing too much current | Open 5V jumper and power servos from external 5V BEC. | | Motor runs only one direction | Broken internal L293D H-bridge | Replace shield. This IC has no short-circuit protection. |

Hardware and key components

The HW-130 Motor Control Shield is a stackable shield designed for Arduino Uno, Arduino Mega, and other compatible boards. It provides a convenient and efficient way to control DC motors, stepper motors, and other high-power devices. The shield features a range of components, including:

Thermal shutdown protection and internal kickback protection diodes. Pinout and Connectivity | IN1 | IN2 | ENA (PWM) |

Dedicated to the two 5V servo motor outputs. Power Supply Configuration

Proper power management is critical when using the HW-130 to prevent resetting or damaging your Arduino. Option A: Shared Power Supply (Short-Term/Low Load Only) Leave the PWR Jumper on the board connected. | | Servos jitter | 5V jumper closed,

The HW-130 motor control shield is a popular, budget-friendly expansion board designed for Arduino Uno and Mega microcontrollers. Based on the classic L293D dual H-bridge driver design, this shield allows hobbyists and engineers to drive multiple DC motors, stepper motors, and servo motors simultaneously.
