SMD‑303 is a step motor driver for simultaneous control up to 3 units of stepper motors. This driver is designed without a case and intended to be built into the system. SMD-303 carries small and middle sizes stepmotors with current per phase below 3.0 A. Microstepping up to 1/16 provides smooth motion. Current reduction function in holding mode can be turned on or off by customer. Standard logic signals Pulse and Dir are used for motion assignment.
