One of the easiest and inexpensive way to control stepper motors is to interface l293d motor driver ic with arduino. The l293d datasheet specifies that this device is a monolithic integrated high voltage, high current four channel driver designed. L293d datasheet, l293d pdf, l293d data sheet, l293d manual, l293d pdf. Driving a bipolar stepper motor with the l293d is very similar to driving a unipolar stepper motor. Up to 2 stepper motors unipolar or bipolar with single coil, double coil, interleaved or microstepping. However, you need to know functions of every pins before it can work better for you.
You can use 2 dc servos that run on 5v and up to 4 dc motors or 2 stepper motors or 1 stepper and up to 2 dc motors this tutorial is for the now ancient v1 motor shield. It can control both speed and spinning direction of any unipolar stepper motor like 28byj48 or bipolar stepper motor like nema 17. L293d motor driver ic pinout, equivalent ics, features and datasheet. The l293d is a dedicated module to fit in arduino uno r3 board, and arduino. Digikey s tools are uniquely paired with access to the worlds largest selection of electronic components to help you meet your design challenges headon. An important notice at the end of this data sheet addresses availability. The l293and l293d are characterized for operation from 0c to 70c. What is the difference between ic l293, l293d, and l293b.

L293, l293d quadruple halfh drivers datasheet catalog. The only difference between driving a unipolar stepper motor and driving a bipolar stepper motor is that there is an extra wire in a unipolar stepper motor you have to hook up. But the numbering is different for different specs and company.
The center shaft has a series of magnets mounted on it, and the coils surrounding the shaft are alternately given current or not. Compare pricing for stmicroelectronics l293d across 38 distributors and discover alternative parts, cad models, technical specifications, datasheets, and more. View l293d d datasheet from stmicroelectronics at digikey. As the shield comes with two l293d motor driver chipsets, that means it can individually drive up to four dc motors making it ideal for building fourwheel robot platforms.
