The datasheet never mentions this, but the shield works fine for light stepper loads (NEMA 17 size max). If you found this article searching for a "better" solution, here's the honest verdict: hw 130 motor control shield for arduino datasheet better

// Start with motors stopped digitalWrite(IN1, LOW); digitalWrite(IN2, LOW); digitalWrite(IN3, LOW); digitalWrite(IN4, LOW); analogWrite(ENA, 0); analogWrite(ENB, 0); The HW-130 is one of the most popular—yet
void setup() pinMode(ENA, OUTPUT); pinMode(ENB, OUTPUT); pinMode(IN1, OUTPUT); pinMode(IN2, OUTPUT); pinMode(IN3, OUTPUT); pinMode(IN4, OUTPUT);
If you’ve ever searched for "HW 130 motor control shield for Arduino datasheet better," 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.
