HW-130 Motor Control Shield for Arduino: A Comprehensive Datasheet and Review

• Jumper ON: Powers the servos from the Arduino's 5V regulator. (Risky for large servos).
• Jumper OFF: You must supply external 5V power to the servo terminal block directly.

const int dir1 = 7;
const int pwm1 = 6;

2 DC motors (bidirectional, with speed control)
1 Stepper motor (unipolar or bipolar)
2 Servo motors (via direct 5V signal pins)


Use a beefier motor driver (e.g., rated 10–30 A continuous) if you need sustained high-current motors, powerful gearmotors, or higher voltages.
For precision current control or regenerative braking, pick a driver with current-sensing and dedicated control features.
