A4988 Stepper Motor Driver Module with Heat Sink For 3D Printer (Red)
A4988 Stepper Motor Driver is a complete micro-stepping motor driver with a built-in translator for easy operation. The product can be full, half, 1/4, 1/8, and 1/16 step mode to operate bipolar stepper motor output drive capacity of up to 35 V and ± 2 A. A4988 includes a fixed off-time current regulator, the regulator can slow or mixed decay mode. The converter is the key to the easy implementation of the A4988. In inputting one pulse on the STEP input drives the motor one micros tep. No phase sequence tables, high-frequency control lines, or complex interfaces to programming.
A4988 interface is very suitable for complex microprocessor is unavailable or is overburdened. The micro-step operation, the chopping control in the A4988 automatically selects the current decay mode (Slow or Mixed). In the mixed decay mode, the device is initially set to fast decay in the part of the fixed off-time, then a slow decay in the rest of the downtime. Mixed-decay current control scheme results in reduced audible motor noise, increased step accuracy, and reduced power consumption.
Internal synchronous rectification control circuitry to improve the pulse-width modulation (PWM) power consumption when operating. Internal circuit protection includes thermal shutdown with hysteresis, under-voltage lockout (UVLO) and crossover current protection. Special power-Sort.
If you want to control the stepper motor with this motor driver, you will need a few essential components like Arduino, breadboard, jumper wires, batteries, and power supply.
Features:
- Simple step and direction control interface
- Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
- Automatic current decay mode detection/choice.
- Mixed with slow current decay mode
- Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection
- Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates

1. What is A4988 stepper motor driver?
- The A4988 is a complete microstepping motor driver with an integrated translator for ease of use. It is intended for use with bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step modes, with output drive capacities of up to 35 V and 2 A.
2. Which driver is best for the stepper motor?
- The A4988 stepper motor driver is the best driver for the stepper motor. The A4988 is a complete micro stepping motor driver with an integrated translator for ease of use.
3. Are all stepper drivers the same?
- Stepper motor drivers vary in complexity. Modern drivers can be used with a variety of stepper motor types. Typically, the user can configure a specific motor at the time of installation. Stepper motor drivers, on the other hand, are generally simple devices.
4. What is the purpose of a stepper driver?
- A stepper motor driver is a motor driver that is designed to drive a motor, such as a stepper motor, to rotate continuously by controlling the exact position without the use of a feedback system. This motor's drivers primarily provide variable current control as well as a variety of step resolutions.
