No, the stepper motor is going to drive a pulley to rotate a

<div>The easy driver is for bipolar only,
it's a good choice for small steppers
(NEMA17). <br>

There are many choices on eBay as well,
about $11 will get you a serious CNC
driver for larger steppers (NEMA23).<br>

What resolution and speed are you looking to
achieve? <br>
</div>
The mass you are rotating, is it heavy and
will you require fast start and stop?<br>

<br>
I'm pretty new to electronics and I'm having
trouble choosing a stepper<br>
motor for a project I'm working on.<br>
<br>
I'm ordering from robot shotp, and it looks
like this EasyDriver board<br>
(<a moz-do-not-send="true"
href="https://secure.robotshop.com/ca/en/sfe-easydriver-bipolar-stepper-motor-driver.html"
target="_blank">https://secure.robotshop.com/ca/en/sfe-easydriver-bipolar-stepper-motor-driver.html</a>)<br>
will let me control whichever motor I end up
choosing, but the number of<br>
motors on robotshop is pretty intimidating.<br>
<br>
I'm going to be spinning a small platform so I
don't need a lot of<br>
power. Basically, I'm wondering whether I need
a bipolar or unipolar<br>
motor? What kind of voltage? Amperage? Any
help would be appreciated<br>
