The STMicroelectronics AEK-MOT-SM81M1 evaluation board is designed to drive a bipolar stepper motor in micro-stepping mode, with coil voltage monitoring for stall detection. This application board features the automotive-grade L99SM81V stepper motor driver with embedded power MOSFETs and a comprehensive set of I/Os for MCU control and feedback signalling using SPI communication through a 12-pin male connector or two 5-pin connectors on the board. 5 V internal linear voltage regulator
Input operating voltage range from 6 V to 28 V
Output current up to 1.35 A
BEMF monitoring for stall detection.
