The UnoDrive is a constant current stepper motor driver. It receives step and direction signals from the controller and can drive motors with up to 40 volts to maximize the high speed performance. The UnoDrive can be used in conjunction with our OptiStep Plus, MN100 or MN400 motion controllers or with any controller capable of producing TTL compatible step and direction signals.
