This is ULN2003 Stepper Motor Driver Board, small size and easy to use. It uses the ULN2003 driver chip to amplify the control signal from the Arduino. This Ultra Lightweight and cheap option commonly used to run and control the small applications stepper motors.

It uses the ULN2003 DARLINGTON ARRAYS to drive the 4-phase 5-wire stepper motor (5v-12v).It’s easy to use Arduino or other development platform to drive the stepper motor by this diver board.

How to Control Stepper:-

The step motor is to a machine to convert pulse to angular displacement. So if you give stepper driver a certain pulse signal, it will drive step motor to a certain angle. you can control the angle the stepper moved by the number of the pulse. And you also can control the speed of the stepper rotate by the frequency of the pulse.

A4988 Module is a  Smaller and Cheapest breakout board for Allegro’s A4988 Stepper Motor Driver. It has many advantages including adjustable current limiting, over temperature and over current protection. It has five different stepping resolution and has a wide operating voltage range from 8 volt to 35 volts and can deliver current upto 1 Amp per phase.

The A4988 is a complete micro-stepping motor driver with built-in translator for easy operation. It is designed to operate bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step modes, with an output drive capacity of up to 35 V and ±2 A. The A4988 Motor Driver includes a fixed off-time current regulator which has the ability to operate in Slow or Mixed decay modes.

The translator is the key to the easy implementation of the A4988. Simply inputting one pulse on the STEP input drives the motor one micro-step. There are no phase sequence tables, high frequency control lines,or complex interface sto program. The A4988 interface is an ideal fit for applications where a complex microprocessor is unavailable or is overburdened. During stepping operation, the chopping control in the A4988 automatically selects the current decay mode, Slow or Mixed.

In Mixed decay mode, the device is set initially to a fast decay for a proportion of the fixed off-time, then to a slow decay for the remainder of the off-time. Mixed decay current control results in reduced audible motor noise, increased step accuracy, and reduced power dissipation.

A3967 Stepper Motor Driver For Arduino is the latest version of EasyDriver v4.4. It provides greater flexibility and control over your stepper motor compared to the older versions.

It is a simple to use stepper motor driver, compatible with most microcontrollers that can output a digital 0 to 5V pulse (0 to 3.3V pulse if you solder SJ2 closed on the EasyDriver). The module requires a 7V to the 30V power supply for a motor. The module has an onboard voltage regulator for the digital interface that can be set to 5V or 3.3V.

Connect a 4-wire stepper motor and a microcontroller and you’ve got precision motor control! EasyDriver drives bi-polar motors and motors wired as bi-polar. i.e. 4, 6 or 8 wire stepper motors. The microstep select (MS1 and MS2) pins of the A3967 are broken out allowing adjustments to the micro-stepping resolution. The sleep and enable pins are also broken out for further control.

The A3967 is a complete microstepping motor driver with builtin translator. It is designed to operate bipolar stepper motors in full-, half-, quarter-, and eighth-step modes, with output drive capability of 30 V and ±750 mA. The A3967 includes a fixed off-time current regulator that has the ability to operate in slow, fast, or mixed current-decay modes. This current-decay control scheme results in reduced audible motor noise, increased step accuracy, and reduced power dissipation.

The translator is the key to the easy implementation of the A3967. By simply inputting one pulse on the STEP input the motor will take one step (full, half, quarter, or eighth depending on two logic inputs). There are no phase-sequence tables, highfrequency control lines, or complex interfaces to program. The A3967 interface is an ideal fit for applications where a complex μP is unavailable or over-burdened.

Internal circuit protection includes thermal shutdown with hysteresis, under-voltage lockout (UVLO) and crossovercurrent protection. Special power-up sequencing is not required. The A3967 is supplied in a 24-pin SOIC, which is lead (Pb) free with 100% matte tin leadframe plating. Four pins are fused internally for enhanced thermal dissipation. The pins are at ground potential and need no insulation.

The Double BTS7960 43A H-Bridge High-Power Stepper Motor Driver Module is; a fully integrated high current H bridge for motor drive applications using the BTS7960 high current half bridge. the BTS7960 is part of the NovalithICTM family.
