I recently bought some cheap ebay stepper motors to experiment with (http://www.ebay.com/itm/221393363619?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649). Given these are 5v motors, if I were to control them via Teensy 3.0, I'm wondering what kind of voltage level converter I need.
I assume I need to plug in the power to the motor to 5v, either VIN or a separate 5v power source.
I imagine I need to do level converters for each of the 4 pins. Is the stepper motor communication one way, or do I need use level converters that are bi-directional? Are some of the 4 pins always output pins and some always input? Or is it a mixture? If I were to go to the Teensy 3.1, would I need level converters at all (i.e. would I be able to drive the motor from 3.3v on the Teensy, and any input from the motor would work on the 5v tolerant pins).
Assuming I need to do level converters, would I need to use a fast acting converter like the 74HCT245 that is recommended for neopixels (but that might not work with bi-directional pins).
Is there a level converter that is recommended for stepper motors?
Are there any limits on the Teensy to having more than one stepper motor?
I assume there are no differences in wiring the Stepper motors between the standard Stepper library and the AccelStepper library?
