Stepper Motor Driver with A4989

Design by: 4972

Bipolar stepper motor driver for small, medium, and large size motors. - runs at 12V to 35V; - continuos output current of several amperes (depends on the used power mosfets); - drives in full step, 1/2 step, 1/4 step, 1/16 step (selectable with a dip-switch); - selectable decay (through a dip-switch) for best match with the motor; - auxililary output of 5Vdc for give power to connected circuits; - heatsink not required (but there are holes to mount a heatsink on the power mosfets) Contact me for detail! ;-)
