## Description

This stepper motor is a little different than the large NEMA-17 types you may be used to. These are often used in gauges for motorcycles and cars to replace the old-style fully-analog type. They have extremely fine step precision of about 1/2 a degree per step, 600 steps for single stepping, fast response for quick movements, and a range of ~315° degrees. Their smooth motion makes good for small projects that need a dial indicator, and more precision motion than you may get with a needle gauge.

Since this is a bi-polar stepper motor you do need to have some sort of H-Bridge to drive it. A [L293D](https://core-electronics.com.au/dual-h-bridge-motor-driver-for-dc-or-steppers-600ma-l293d.html) or [TB6612](https://core-electronics.com.au/adafruit-tb6612-1-2a-dc-stepper-motor-driver-breakout-board.html) will do the job nicely. If you have a microcontroller that can drive 200 ohm loads you might be able to use the direct pins without extra MOSFETs, just remember to include kickback/flyback protection diodes!

Note that the motor is quite 'weak', not good for moving anything but a light indicator. Adafruit include a red-line dial that fits nicely on top by pushing onto the needle shaft.
