Hw 130 Motor Control Shield For Arduino Datasheet ((full)) Free May 2026
HW-130 Motor Control Shield
The (also known as the L293D Motor Shield ) is a versatile driver board based on dual L293D H-bridge chips, allowing you to control multiple motors from an Arduino. Key Technical Specifications Driver Chips : Two L293D ICs and one 74HC595 shift register.
to expand 3 Arduino pins into 8 control lines for the H-bridges. Direction Control
Warning
: 9V alkaline batteries are not recommended as they often cannot provide sufficient current for multiple motors under load. L293D Based Arduino Motor Shield hw 130 motor control shield for arduino datasheet free
Polarity:
Double-check the + and - on the EXT_PWR block. Reversing polarity can fry the L293D chips instantly.
