Hi All,
I understand that this thread is a little old, but there is a lot of relevant information that seems silly to force being explained again in a new thread.
I've purchased a similar set up to what's described here and am having similar issues. The motor is not turning, but rather is emitting a faint vibration.
For testing purposes, I'm using the same sketch discussed here, Ardunio sample --> stepper_oneRevolution
The steps are set to 200 with the function call as --> Stepper myStepper(stepsPerRevolution, 1, 3, 2, 4)
Board and Driver:

Power Supply (5V 3A):
NEMA 17 motor (2.2V 2A per coil):
I'm wondering if the motor needs more current that the power supply can provide?
Although, it seems like it should be providing over 2A total, given the ESP8266 power requirements are quite low. Shouldn't 1A per coil be enough to make it turn?
Thanks for your guidance
Chris
