The The MikroElektronika's Stepper 16 Click is a compact add on board that contains a micro stepping stepper motor driver. This board features the NCV70517, an SPI and I/O configurable motor driver for bipolar stepper motors from ON Semiconductor. The NCV70517 contains a current translation table and takes the next micro step depending on the clock signal on the NXT input pin and the status of the DIR pin. It also provides an error message if an electrical error, an under voltage, or an elevated junction temperature is detected. This Click board is fully compatible with the automotive voltage requirements and ideally suited for general purpose stepper motor applications in the automotive, industrial, and applications with fluctuating battery supplies.
