Pololu 8-35V 2A 単一2極ステッピングモータドライバ A4988

This is a really nice stepper driver, with good instructions so you can easily use the micro-stepping modes, current limiting, etc., to get the max performance out of your motor. Even if you don't want to use the features, just leave the mode pins unconnected and you have a simple 2-wire interface to run the 4-wire motor. You can't beat this device for the money. Does get hot if you leave the enable pin on.

I have a 12 volt stepper salvaged from a disk drive. I connected it using an Arduino Uno. Ran the sketches with no problems.

Needed to add heat sinks at the bottom of the pcb where the thermal vias are and a copper heat sink on the top of the chip; the way I've used it temps got >>80 degrees C; now it works fine. Sometimes my steppers are showing strange things (stepping back instead of forward); probably a temp thing because it only happens after driving them for a while. For "lights" stuff this is more than ok!

Pretty much plug and play by following the pin layouts on the datasheet. Only requires step and direction inputs to run. Works with bipolar and unipolar stepper motors. More info can be found on the pololu page.

Très bon produit fonctionne très bien avec linux cnc et tous les moteurs bipolaire et hybride
