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.
Want to controller stepper Motor from Arduino, Raspberry Pi or any other Micro-controller? Well then this stepper motor driver will simplify your coding and will give you more flexibility in controlling the stepper motor.
The DRV8825 stepper motor driver carrier is a breakout board for TI’s DRV8825 micro-stepping bipolar stepper motor driver. The DRV8825 features adjustable current limiting, over-current and over-temperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 – 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling).
This product is a carrier board or breakout board for TI’s DRV8825 stepper motor driver; we therefore recommend careful reading of the DRV8825 datasheet before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2.2 A output current per coil.
The L9110S dual channel h-bridge motor driver module is a compact board that can be used to drive small robots. This module is based on L9110 Motor Driver IC. This module has two independent motor driver chips which can each drive up 800mA of continuous current. The boards can be operated from 2.5 volt to 12 Volt enabling this module to be used with both 3.3 Volts and 5 Volts microcontrollers. A set of female header pins is used to connect this module to a micro controller. The motors are attached via two sets of screw terminals.
A PWM Pulse Width Modulation signal is used to control the speed of a motor and a digital output is used to change its direction. This module can also be used to drive a single four line two phase stepper motor. Four holes make this board easy to mount onto your robot or other project.
DRV8833 is a dual H-bridge motor driver IC that can be used for bidirectional control of two brushed DC motors at 2.7 V to 10.8 V. It can supply up to about 1.2 A per channel continuously and can tolerate peak currents up to 2 A per channel for a few seconds, making it an ideal driver for small motors that run on relatively low voltages. The board ships populated with SMD components, including the DRV8833, and adds an FET for reverse battery protection.
The DRV8833 has a higher peak current rating (2 A per channel vs 1.5 A), optional built-in current-limiting, and no need for externally supplied logic voltage.
