Whilst no extra hardware at all is attractive, at £0.51 (60 cents?) per chip (£0.25 per motor) the ULN2803 will drive steppers at up to 50V / 500mA in Unipolar mode at very little cost.

14. When faced with an unknown stepper motor of small to intermediate size, a very reliable gamble to play is as follows: if it has more than four wires, it's probably a four-pole unipolar motor, 0.9 ...

The Arduino-based evaluation kit (EVK) is said to supports the evaluation of ROHM Semiconductor’s motor driver devices and enables, facilitates and accelerates customers’ developments. Designed as a ...

The Easy-Step 3000 line of advanced stepper motor drive and control systems are designed for unipolar stepper motors up to 35 V and 3 A per phase. The 3000's small size (63.6 26.4 mm) makes it a ...

Afamily of unipolar, twophase, stepper-motor driver ICs is designed to simplify peripheral circuitry design and reduce space while maintaining good reliability. The SLA7070MPR Series, developed by ...

For applications where the microprocessor is overburdened or absent, the SLA7051M constant-current, two-phase unipolar stepper motor driver includes a built-in translator, allowing ...

Check out this inventive use of an MCU and stepper motor by one Alan Parekh. This great looking gear clock tells the time in a unique way. A PIC 16F628A microcontroller with an external 20MHz crystal ...

I like this one - a super impressive Arduino-based barometer for measuring air pressure. There's something satisfying about the link with nature, a tangible connection with outside weather. In a ...

In addition to the 20mm motor size, this motor is also available in 25mm (captive or non-captive option) and 35mm diameter sizes. They can also be customized. Nippon Pulse America Inc. , 540-633 ...
