Note: It takes 10 of these cables to break out every pin on the Mega Pro Mini, so make sure that you order enough for your application.
Trigger inputs can be connected directly to switches and buttons, or to digital outputs from sensors or another microcontroller. Alternate functions can be specified using a free cross-platform GUI application, and allow triggers to play sequential or random tracks, pause and resume groups of tracks and even control volume.
When using a current limiting driver such as the Easydriver or Big Easydriver, a 12 volt power supply can be used as long as you adjust the current level to 400mA or less. If using a non current limited driver (like a L293D or an H-bridge) you will need to lower your input voltage to keep the motor current below 400mA.
These stepper motors, in particular, are used with the Shapoko CNC machine and offer 125 oz.in of torque and 200 steps per revolution. Additionally, each motor has been equipped with extra long 600mm AWG22 wires, making them ideal for CNC applications.
Note: It looks like the datasheet for this stepper may not be accurate. When connecting this motor to a bi-polar driver you’ll want to wire it according to the wiring diagram in the documents below.
This is a simple, but very powerful stepper motor with a 4-wire cable attached.
These steppers are a great way to get things moving, especially when positioning and repeatability is a concern.
