Hw 130 Motor Control Shield For Arduino Datasheet Page

Here’s a concise review of the HW-130 Motor Control Shield based on typical user documentation and datasheet content available for this popular low-cost Arduino shield.

Is the HW-130 good?

Yes, for: Simple robots, tank drives, small conveyor belts, and learning. It's cheap ($3–$5).

No, for: Precise speed control (the L298N has a non-linear response) or high-torque motors (get a MOSFET-based shield like the Adafruit Motor Shield v2).

Final Recommendation

The HW-130 datasheet describes a capable shield for learning and light robotics (e.g., line followers, small RC cars). hw 130 motor control shield for arduino datasheet

Do not buy this if: You are building a high-power robot, a delivery robot, or something requiring efficiency. The L298P technology is outdated and inefficient (it wastes battery life as heat).

Buy this if: You need a plug-and-play solution to drive two small yellow DC motors (TT motors) or a small stepper motor for a CNC plotter, and you want to avoid messy wiring.

5.4 Two Servo Motors

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). Here’s a concise review of the HW-130 Motor

1.2 Physical Dimensions

• Form Factor: Arduino Uno R3 Shield (fits perfectly on top of Uno, Mega 2560, or Leonardo).
• Connectors: Screw terminals for motor supply and motor outputs; male pin headers for logic signals.

Pinout: The "Missing" Datasheet

The HW-130 doesn't use the standard L298N pin mapping. Here is the actual breakout:

| Arduino Pin | HW-130 Function | | :--- | :--- | | D5 | Motor A Speed (PWM) | | D6 | Motor B Speed (PWM) | | D7 | Motor A Direction 1 | | D8 | Motor A Direction 2 | | D9 | Motor B Direction 1 | | D10 | Motor B Direction 2 |

Warning: Do not trust the silkscreen on cheap boards. Always verify with a multimeter, but the table above matches the standard "L298N Shield" reference design. Form Factor: Arduino Uno R3 Shield (fits perfectly
