Hw 130 Motor Control Shield For Arduino Datasheet Better

If you’ve ever searched for you have likely landed on a handful of cryptic Chinese PDFs, low-resolution pinout diagrams, or forum posts with conflicting wiring instructions. You are not alone. The HW-130 is one of the most popular—yet poorly documented—dual motor driver shields on the market.

When you look at the HW-130, you see a sea of green screw terminals and jumper caps. Here’s what each landmark does: hw 130 motor control shield for arduino datasheet better

: Two L293D motor driver ICs and one 74HCT595 shift register. Motor Capacity : If you’ve ever searched for you have likely

| Function | Arduino Pin | HW-130 Label | Datasheet Mistake | |----------|-------------|--------------|--------------------| | Motor A Enable (PWM) | D10 | ENA | Often mislabeled as "PWM A" | | Motor A Input 1 | D9 | IN1 | Correct | | Motor A Input 2 | D8 | IN2 | Correct | | Motor B Enable (PWM) | D5 | ENB | Often mislabeled as "PWM B" | | Motor B Input 3 | D7 | IN3 | Correct | | Motor B Input 4 | D6 | IN4 | Correct | | Logic Supply (5V) | 5V pin | +5V | Some clones skip this | | GND | GND | GND | Correct | When you look at the HW-130, you see
