## Description

This tiny stepper motor is the same quality and step-size as the big NEMA-17's Adafruit stock, but so cute so it will work with compact CNC builds. 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 600mA 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) [Motor Bonnet for Raspberry Pi](https://core-electronics.com.au/adafruit-dc-stepper-motor-bonnet-for-raspberry-pi.html) or Adafruit's [Feather Motor controller](https://core-electronics.com.au/dc-motor-stepper-featherwing-add-on-for-all-feather-boards.html) & and a wall adapter or lead-acid battery. It's rated for 3.9V, if you have a stepper driver with current limiting, use that to keep the power down. If you have a non-current-limiting driver such as the motor shield/hat/feather Adafruit found 5V DC power worked well to power the stepper controller.The cable has ready-to-go wires - the drive-shaft does not have a D cut in it, but you can clamp to it pretty easily. 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/hat/featherwing, put the wires in this order: Black, Red, skip ground if there is one, Green, Yellow.
