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
Standard L298N modules have physical jumpers for ENA and ENB. On the HW-130 Shield, these are often connected to specific Arduino pins. hw 130 motor control shield for arduino datasheet better
D5 and D10 are unused on most HW-130 boards – they are remnants of other shield designs. Stick to D6 and D9 for PWM. The is a popular, low-cost expansion board for
