The HW-130's versatility allows you to build many different projects.

2 × 5V servo connections (powered by Arduino 5V). Voltage Range (Motors): 4.5V VDC to 25V VDC. hw 130 motor control shield for arduino datasheet better

Power the Arduino via USB and motors via the EXT_PWR terminal.

The is a functional but fragile L293D-based motor shield. To use it successfully:

Unlike many shields, the HW-130 uses a to save Arduino pins. You cannot simply "digitalWrite" to a motor pin. Power the Arduino via USB and motors via

The HW-130 Motor Control Shield is a reliable and efficient solution for controlling DC motors with your Arduino board. With its simple design, wide voltage range, and overcurrent protection, it's an excellent choice for robotics, automation, and other motor control applications. By following this datasheet and example use case, you'll be able to easily integrate the HW-130 shield into your projects and start controlling motors with confidence.

| Problem | Likely Cause | Solution | | :--- | :--- | :--- | | | No power to shield, incorrect wiring, or missing library | Check EXT_PWR connection, ensure motor is in M1/M2, and verify AFMotor library is installed | | Motors spin but Arduino doesn't boot/resets | Motor power brown-out | Remove PWR jumper, ensure external power can supply enough current, separate motor and logic supplies | | Weird/unexpected motor behavior | Shift register not powered or damaged | Ensure shield is seated properly, check if 74HC595 chip is getting 5V, try a different Arduino pin | | Bluetooth module not pairing | Wrong baud rate, power issues | Check baud rate (usually 9600 or 38400), ensure BT module is getting enough current (use external 5V regulator if needed) | | Servo jitters randomly | Servo power drawn from Arduino 5V rail | Power servos from a separate 5V regulator connected directly to battery pack | You cannot simply "digitalWrite" to a motor pin
