Introduction
Our step motor controller is a compact electronics device ensuring stable and flexible control of steper motors used in optomechanics. Several step motor drivers can be stacked together for multi-axis systems. Rigid enclosure design makes the device lightweight and reliable during intensive use. Elimination of hand soldering during manufacturing process of the controller guarantees lowest defect ratio and longest operating time.
