Uses current generated on coils in stepper to act as an encoder
Pretty simple circuit I found, you may have to play with the resistor values to get the output to logic level depending on your steppper.It uses two voltage … Read more
Takes PWM signals then feeds to an H-Bridge
Okey Dokey,  What I Have here is a relatively simple way to control 2 low to mid current motors with no fancy integrated circuits. This is just a nothing special … Read more
