## Description

A stepper motor to satisfy all your robotics needs! This 4-wire bipolar stepper has 1.8° per step for smooth motion and a nice holding torque. The motor was specified to have a max current of 350mA so that it could be driven easily with an [Adafruit motor shield for Arduino](https://core-electronics.com.au/adafruit-motor-stepper-servo-shield-for-arduino-v2-kit-v2-0.html) (or other motor driver) and a wall adapter or lead-acid battery.
 
 Some nice details include a ready-to-go cable and a machined drive shaft (so you can easily attach stuff). Adafruit drove it with an [Adafruit motor shield for Arduino](https://core-electronics.com.au/adafruit-motor-stepper-servo-shield-for-arduino-v2-kit-v2-0.html) and it hummed along nicely at 50 RPM. To connect to Adafruit's shield, put the wires in this order: Red, Yellow, skip ground, Green, Brown (or Gray)
