Hw 130 Motor Control Shield For Arduino Datasheet Better [better]

// Motor A #define ENA 6 // (if jumper removed) or set to 255 if hard-wired #define IN1 12 #define IN2 13

: Provides 0.6A continuous current per bridge (1.2A peak) with thermal shutdown protection.

The L298N chip loses under load. If you feed it 6V, your motor sees only ~4.5V. For full performance, use 9V or 12V batteries. hw 130 motor control shield for arduino datasheet better

The HW-130 Motor Control Shield is suitable for a wide range of applications, including: // Motor A #define ENA 6 // (if

3-pin headers (GND, VCC, PWM) for 5V servos.

A: This is almost always a power issue. First, ensure you are using an external power supply for the motors via EXT_PWR . Second, verify that the 5V-EN jumper has been removed. Finally, check that all ground (GND) connections are common between the Arduino, the shield, and the external supply. For full performance, use 9V or 12V batteries

Third, it would address — a notorious weak point. The HW-130 often shares ground between logic and motor supply, but a good datasheet would show separate star grounding for high-current loads. It would include a table of maximum continuous current per channel (e.g., 1.2A without heatsink, 2.5A with forced airflow), derated for ambient temperature. It would even recommend a specific capacitor (e.g., 1000 µF, 25V) across the motor supply to prevent resets. Current “datasheets” treat power as an afterthought; better documentation treats it as a first-class constraint.

The most significant difference is that the , while an L298N can supply over 2A. For small robots with small motors, the HW-130 is ideal. For anything larger, an L298N or a more powerful shield is necessary.
