Geared Stepper with Driver

I got some of these to try with a drawbot and other projects.

It looks like they need 4 arduino pins so I will need 8 pins to control the two motors. Or I could try and run them from the motor shield.

The only challenge is how to mount a spool to those short shafts. I think they are 6mm with two flats on them.

Here are the claims from one of the sellers:

This is a 5v 28YBJ-48 Stepper Motor Geared 4 Phase 5 Wires for Electonic Experiment DIY, such as ATmega328 2560 PIC 51 AVR microcontrollers. You can make good use of it for your experiment with sparkle idea.

* 100% Brand New
* Phase : 4
* Current : 92mA
* Resistance : 130 Ω
* Voltage : 5V DC

Another supplier:

5V all-metal micro stepper motor with 1:85 gear reduction gives plenty of smooth power at an incredibly small package. We’ve included a horn that you can easily adapt to your application. An internal slipper clutch protects the gears from sudden shock or overload. Motor comes with a durable bronze (not plastic) shaft. We have not found any other gear-reduced stepper motors come close in terms of size, performance, and quality. These motors are custom made to our specs. You will not find this motor anywhere else.
Type: Unipolar 5 wire Stepper Motor (1 Common, 4 Coils)
Rated Voltage: 5V
Voltage Range: 3-9V
Resistance per phase: 50 Ohms
Gear Ratio: 1:85
Step Angle: 7.5 degrees/85
No load pull-in Frequency: >500Hz
No load pull-out Frequency: >900Hz
Noise: <34dB
Weight: 24g / 0.88oz.
Datasheet Included!

 

Our MOSFET Driver board will dramatically cut down on size, wiring, and time. This board is capable of handling loads up to 2.5 Amps. Sequencing and timing will still need to be done via a stepper motor controller or your MCU.

 

MOSFET DRIVER Specs:

Supply Voltage: 3V – 15V

Max Load: 2.5 Amps

Control (Timing) Signal: 5V typical, 8V Max

On-State Resistance: .085 Ohm
