The HW-130 shield connects to the Arduino board via the following pins:
int enA = 6; // PWM speed for Motor A int in1 = 4; int in2 = 7;
The is a multi-channel motor driver shield based on the L293D chipset. It is a popular, low-cost clone of the original Adafruit Motor Shield v1 , designed to plug directly onto an Arduino Uno Go to product viewer dialog for this item. or Go to product viewer dialog for this item. . 1.

The HW-130 uses the following :
HW-130 Motor Control Shield is a popular clone of the original Adafruit Motor Shield v1 . It is designed for plug-and-play use with Arduino Uno
The is a popular, low-cost expansion board for the Arduino Uno and Mega, designed to drive a variety of motors simultaneously with minimal wiring. It is technically identical to the classic Adafruit Motor Shield v1 design and is powered by dual L293D dual-channel H-bridge drivers. Technical Specifications The HW-130 shield connects to the Arduino board
| Feature | HW-130 (L298N) | TB6612FNG | L293D | |---------|----------------|-----------|-------| | Max current | 1.5A (real) | 1.2A | 0.6A | | Voltage drop | ~2V | ~0.5V | ~1.5V | | PWM frequency limit | 25kHz | 100kHz | 5kHz | | Heat generation | High | Low | Medium | | Datasheet quality | Poor | Excellent | Good |
| Problem | Likely cause | Fix | |---------|--------------|-----| | Motors not moving | No external power to shield | Connect 6–9V to EXT_PWR | | Motor only goes one direction | L293D channel damaged (common) | Replace shield or use unused channel | | Servo jitters | Servo power taken from Arduino 5V | Power servos directly from external 5V BEC | | Arduino resets when motor starts | Motor current spike | Add large capacitor (470–1000µF) across EXT_PWR terminals | | Overheating | Motors draw >600mA | Reduce load or use MOSFET driver (e.g., L298N) |
Some revisions of the HW-130 route ENA/ENB to Analog pins A0/A1 or require jumpers to be removed to access PWM. If your motors run at full speed regardless of code, check if ENA/ENB are hard-wired via jumpers on the board. It is designed for plug-and-play use with Arduino
The is a functional but fragile L293D-based motor shield. To use it successfully:
// Motor B backward digitalWrite(motorBPin1, LOW); digitalWrite(motorBPin2, HIGH);
