Description
The A4988 Stepper Motor Driver (1.5A) is a micro-stepping driver with built-in protection features, including thermal shutdown, over-current, and UVLO (under-voltage lockout) protection. It allows for easy operation of bipolar stepper motors with simple step pulses and supports full, half, quarter, eighth, and sixteenth microstep resolutions. Key features are its adjustable current limiting, automatic selection of slow or mixed current decay modes, and a broad operating voltage range from 8 V to 35 V.
Features
- 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)
