DRV8825 Stepper Motor Driver Carrier, High Current (md20a)

This original version of our DRV8825 stepper motor driver carrier has been replaced by a newer version that can more easily be used as a drop-in replacement for our A4988 stepper motor driver carriers. The only difference is that the newer version connects the sleep and fault lines through a resistor, making it more straightforward to use in very specific situations described in more detail on the product page. Generally speaking, most users should not notice any difference between the two driver versions.
