A4988 Stepper Motor Driver

Stepper Motor Drivers that provides all control functionalities over Nema stepper motors. 

• A simple steps and direction control interface
• six different steps resolutions: full step, half step, 1/4-step1/8-step1/16-step, 1/32-step
• CAN interface directly with 3.3 V and 5 V systems
• Over-temperature thermal shutdown, overcurrent shutdown, undervoltage lockout
• short to ground short circuit load protection
• 4 Layer 2 oz copper PCB, in order to improve heat dissipation
• exposed solder ground below the bottom of the driver IC on the printed circuit board pad
• module size, pin and interface matching A4988 stepper motor driver operators in many ways
• adjustable current control lets you set a potentiometer, which lets you use the stepper motor's rated voltage or more, in order to achieve a higher rate of maximum output current step
• Intelligent chopping control automatically selects the correct current decay mode (fast decay or slow decay)
• Maximum 45 V supply voltage

• built-in voltage regulator (the need for any external logic supply voltage)
