| HW-130 Function | Arduino Pin | |------------------------|-------------| | Motor A Direction 1 | D8 | | Motor A Direction 2 | D9 | | Motor A Enable (PWM) | D10 | | Motor B Direction 1 | D11 | | Motor B Direction 2 | D12 | | Motor B Enable (PWM) | D13 | | External Power Input | Vin (or separate terminal) | | GND | GND |
The speed control (PWM) pins are mapped directly to the Arduino: Controls DC Motor 1 (M1) speed PWM Pin 3: Controls DC Motor 2 (M2) speed PWM Pin 5: Controls DC Motor 3 (M3) speed PWM Pin 6: Controls DC Motor 4 (M4) speed Power Supply Configuration
Despite its low cost, the HW-130 shield offers a robust set of features.

| Parameter | Value | | :--- | :--- | | | L298P (Dual Full-Bridge Driver) | | Operating Voltage (Logic) | 5V (Supplied by Arduino) | | Operating Voltage (Motor) | 6V – 12V (Recommended), Max 25V | | Output Current (Per Channel) | 0.5A – 1A (Nominal), Max 2A (Peak) | | Control Logic Voltage | 5V Compatible | | Thermal Protection | Built-in Heat Sink | | Dimensions | Standard Arduino Shield Size |
The shield is designed to "piggyback" directly onto an Arduino Uno or Mega. Motor Connections Screw terminals for DC motors. Stepper 1: Uses M1 and M2 terminals. Stepper 2: Uses M3 and M4 terminals. Servo 1 & 2: Standard 3-pin headers (GND, 5V, Signal). Power Management EXT_PWR Terminals: External power input for motors.
Used to interface with the 74HC595 shift register for direction control. Digital 9, 10: Used for Servo 1 and Servo 2 control. Stepper 1: Uses M1 and M2 terminals
The center terminal on the 5-pin blocks acts as the ground/common return. Servo Connections Servo 1: Connected directly to Arduino Digital Pin 10 . Servo 2: Connected directly to Arduino Digital Pin 9 . Power Supply Terminals
