This tiny stepper motor is the same quality and step-size as the big NEMA-17’s we 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, Motor Bonnet for Raspberry Pi or our Feather Motor controller & 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 we 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. We drove it with an Adafruit motor shield for Arduino, and it hummed along nicely at 50 RPM. To connect to our shield/hat/featherwing, put the wires in this order: Black, Red, skip ground if there is one, Green, Yellow.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
