The HW-130 does not have dedicated servo headers, but you can connect signal wires to D9 and D10 (6–7.2V servos need separate external supply).
Strip your motor wires, insert them into the desired screw terminals (M1–M4), and tighten them securely with a precision screwdriver. 5. Software Configuration and Programming
The offers an excellent balance of power and simplicity for Arduino-based robots. By using two L293D chips, it provides independent control over multiple motors, making it indispensable for 2-wheel or 4-wheel drive platforms. If you're using this for a complex project, tell me: What type of motors (DC or Stepper) are you using? What is the voltage of your motor battery? hw 130 motor control shield for arduino datasheet
The HW-130 features a dedicated terminal for external power. Because Arduino pins cannot provide enough current for motors, you should connect an external battery pack (typically 6V–12V) to the terminals.
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.

Troubleshooting Tips
3-pin headers (Signal, VCC, GND). These are usually powered by the Arduino 5V line. Power Terminals EXT_PWR: External power supply terminal ( −negative GND: Connects to the common ground of your motor battery.
The core value of the HW-130 is its ability to serve as a robust power intermediary. An Arduino Uno microcontroller's digital pins cannot safely deliver the current required to drive a physical motor without suffering immediate overcurrent destruction. This datasheet guide breaks down the full architectural specifications, pin configurations, power schemes, and software implementation for the HW-130 module.
