Adafruit Mini Stepper Motor - 200 Steps - 20x30mm NEMA-8 Size

This tiny stepper motor boasts exceptional performance while accommodating compact CNC builds. With a 1.8° per step resolution, it delivers smooth motion and impressive holding torque. Its maximum current specification of 600mA allows easy driving with various controllers like the Adafruit motor shield for Arduino, Motor Bonnet for Raspberry Pi, or Feather Motor controller.

Optimized for 3.9V operation, it supports current-limited stepper drivers to maintain low power usage. When using non-current-limiting drivers, a 5V DC power source efficiently powers the stepper controller. The drive shaft design permits easy clamping despite the absence of a D cut.

The pre-wired cable simplifies setup, though note that wire colors may vary. For Green/Black/Yellow/Red motors, connect as Black, Red, Green, Yellow; for Yellow/Red/Orange/Blue motors, connect as Red, Blue, Yellow, Orange. Tested with an Adafruit motor shield for Arduino, the motor runs smoothly at 50 RPM.
