Hi! I'm up to a project where I want to run a remote stepper motor via wifi. 
My plan so far is to do it from a "Easy driver" (http://www.schmalzhaus.com/EasyDriver/E ... iption.png).
Then all I need is something that can receive a wifi signal, start a script and output through 2 i/o pins(only high and low).
The pins will tell direction(high/low) and steps. Steps are made 1 each time it goes from low-high.
So now the question comes! What is the smallest ESP I can use for this? Can it send a PWM signal for the steps?
Should I store a script on the ESP or have it react to wifi signals for each step?
Can I run it on 5V? The Easy Driver has a 5V output.
