Hw 130 Motor Control Shield For Arduino Datasheet [new]

HW-130 Motor Control Shield for Arduino — Technical Report Summary

The HW-130 is a dual-channel motor driver shield designed for Arduino-compatible boards. It provides bidirectional control of two DC motors (or one stepper), PWM speed control, direction control, and optional current sensing and braking. Typical uses: robotics, small vehicles, and motorized prototypes.

Key specifications

Driver type: Dual H-bridge integrated driver IC (common variants: L298N, TB6612FNG, or similar). Supply voltage (motor): typically 5–12 V (check exact variant; some accept 2.5–13.5 V). Logic supply: 5 V (from Arduino). Continuous motor current per channel: typically 1–2 A (with heat-sinking); peak stall current up to 3–5 A for short durations. PWM frequency: compatible with Arduino PWM (≈490 Hz on most pins; some shields route to pins with 980 Hz). Control signals: IN1/IN2 (direction) + PWM (speed) per channel; enable pins may be present. Protection: flyback diodes, thermal shutdown, overcurrent protection (depends on driver IC). Additional features: onboard screw terminals for motor/battery connection, pin headers for Arduino stacking, indicator LEDs for power/drive status, logic-level MOSFETs on some revisions. hw 130 motor control shield for arduino datasheet

Pinout and connections

Power:

VIN/MOTOR+: External motor power input via screw terminal or VIN jumper. GND: Common ground with Arduino and battery. 5V: Logic supply from Arduino; some variants include a regulator for 5V from motor supply—check jumper. HW-130 Motor Control Shield for Arduino — Technical

Motor outputs:

M1A, M1B — Motor 1 terminal A/B. M2A, M2B — Motor 2 terminal A/B.

Control pins (typical mapping to Arduino digital pins): Continuous motor current per channel: typically 1–2 A

Channel A: IN1 (direction), IN2 (direction), PWM (speed) Channel B: IN3, IN4, PWM Sometimes labeled ENA/ENB or A1/A2.

Optional: current sense pins (ISENx) expose voltage proportional to motor current.
