The HW-130 Motor Control Shield is a versatile expansion board for the Arduino Uno and Mega, designed to drive multiple motors simultaneously using only a few pins. It is a high-power, multi-functional shield based on the L293D driver chipset and is widely used for robotics projects. Technical Specifications Adafruit Motor Shield
To unlock the full potential of the HW 130, you must remove the ENA/ENB jumpers (JP2 and JP3). Without these jumpers, you manually control those pins via PWM. hw 130 motor control shield for arduino datasheet
Based on the pinout above, here is the truth table. To spin a motor, you set one direction pin HIGH and the other LOW. To brake, set both HIGH. The HW-130 Motor Control Shield is a versatile
